Any motorcyclists on this forum?

I don't think that I would trust the 25 year old me with that amount of horsepower.
That's the big controversy .

The old me, now, would not go near a Yamaha TZ750 (vintage even for the young me at 1989) .
The young me back then went to immense lengths to ride one so to see what all the fuss was about.


2-strokes for me only, even now, the difference is that the vintage YZ490 won't kill you in a heartbeat as the racing Yami could do.
 
Indeed. I reckon that it has to be a very good thing that modern bikes with 200+ horsepower, also have various optional levels of traction control and ABS etc.

Aye, the TZ750 has to be one of the most crazy motos ever. Think it was nicknamed "The Beast" by Kenny Roberts. IIRC, aparently he said "They don't pay me enough to ride that thing!".

A brutal, narrow powerband, nasty vintage tyre technology, and a chasis with all the stiffness of cooked pasta.
(Diapers in yer leathers optional lol)

Got a picture of the blueprint design drawing of the flatrack version on my bathroom wall.

There's no word to describe what "response" means unless you ride something like that.
Coming from 2-strokes back then, the fool me thought that would be trivial. Nope.

Thank God I had enough road ahead of me so to swallow the shock and then treat the gas as if I was about to launch a nuclear strike.
My mind was telling me to lock at each turn so I won't accidentally move my right hand even a cm.

That's the thing about been young, fear and excitement can be the same thing.
 
That's the big controversy .
MotoGP riders start racing as children on minibikes. :)
P.S. The 200 hp and 300 km/h of the V4 S are a lot but if you are on the roads and not on the track you have to respect the speed limits (unless you are on the German autobahns).

Totally agree (now :) )
(but time to reach the given speed limit has to be accounted for too )
 
Unfortunately: That oil leak will need to be fixed before doing anything else: some of that oil WILL get on the rear tire & down he goes (no matter how well he cleans it up before riding).
Speaking of the oil on the rear tire. I was test riding a Suzuki street bike with ~12,000 km on it to see if it was suitable for me to buy it. I was like a son with the motorcycle shop owners and even lived with them for 6 months when younger so they told me make sure this bike fits and take it over the mountain pass and around the loop and back to the shop. So there I was cruising in bear country up on the mountain pass arcing through a corner at ~140 kmh and I felt the bike get very slippery. Before I rode street bikes I rode dirt bikes, was a very aggressive rider and rode big mountains on enduro 2 stroke rides in some very treacherous terrain and was very accustomed to hanging out the back end and sliding sideways and all that jazz after ~35,000 km dirt riding as was indicated on the speedos. So when the street bike was sliding off the road at ~140 kmh up on that mountain pass I never was scared and I just did what I did in the dirt and got it back in the middle of the lane and gently used the brake and realized the back brake was not good so I only used the front and got it down to walking speed and then came to a stop. I got off the bike and looked back and there was a big dark stain on the road. LoL. So I walked the bike back up the highway to a rest stop about 150 meters away and sat there listening for cars and flagged down a guy in a pickup truck and asked him to telephone the bike shop when he got into town and he said he will do that. So ~1 hour and 30 minutes drive into town, then time to process and then time to drive back to me. I knew I was going to be waiting for hours for the bike shop to get organized and drive up to me in their truck.~ 4 hours I sat there on the concrete barrier at the edge of the very high embankment overlooking a forest and a couple of bears wandered across the highway, cars honking their horns at them and me sitting there watching the cars and the bears a jog distance away. I grew up in black bear country. Grizzly are said by the game and wildlife officers to only exist when in your region when they travel between 2 different regions where they are common. So I only saw one grizzly in 20 years there but I saw many many black bears including one day a pack of ~14 of them. I hate black bears. When they attack they instinctively tear off the scalp and the face and leave the person with horrific injuries. They are awkward and unpredictable and maybe a person goes 200 bear encounters and no attack but that single attack can be horrific. So for ~4 hours I sat there on a beautiful sunny day way up that mountain pass expecting a bear to come walking up over the edge right to me. LoL. The bike shop owners arrived in the truck, expected to see a bike with an entire side bent and scratched from sliding down the road and expected me to be banged up and bloody but where amazed after seeing the stain down the road and then seeing the bike in perfect condition other than a very oily rear end. The father of the family was very obviously angry that the oil drain plug fell out and apologized profusely. The oil drain plug had been stripped by the previous owner that traded the bike in and the threads where good enough to get the bolt tightened but it vibrated loose and fell out. So they Heli coiled the threads and fixed it and I bought the bike and it was a wonderful bike and sustained redline for hours at a time as I put on ~40,000 km over 2 summers.

The control unit is obviously a computer. He tells me that if you set it to "wet" mode, for example, the bike cuts power by half, modifies the rear suspension, and modifies the ABS, which, on a motorcycle, also interprets and reads lateral lean.

P.S. I would never spend €30,000 or more on a motorcycle. I've owned every possible version of the Vespa, but it's his money, and as long as he's aware of the potential dangers, I'm not worried.

Wow. Kudos. Doubt many folks could save a slide like that. Dropping a sump plug is one of those nightmare scenarios for sure. And the reason I always check thread condition on the sump plug on any bike I buy secondhand at first oil change. It's amazing how many get wrecked due to having alloy sumps and ham fisted owners. Had a Katana 11 which had it drilled and lock wired, due to being raced previously. Not a bad idea on roadbikes too.
I am also always super careful to carefully clean threads and use threadlock when doing an oil change for this reason. Nasty.

It was a very awkward and weird feeling to have oil on the rear tire. Not as extreme as a full on dirt bike slide but a subtle weirdness and gradual tendency to want to slowly move towards the outside of the corner where a huge embankment was and that alerted me to a danger I knew was impending. I again attempted using the rear brake when I was down to ~50 kmh and that was a obvious bad move so I instantly stopped even trying that and went all in on the front brake. For some reason when I was down really slow and was very unsure of myself and what the heck was occurring the rear tire slipped sideways without me even touching the rear brake. I broke a frame on a 2 stroke enduro ride when I was jumping off huge grass sod balls down by the Columbia River where these huge grass growths occur and they are great fun to wheely off and jump high vertically into the air. I came down hard and broke the frame. The feeling after the frame was broken right in front of the engine below the frame engine bolt mount was the same feeling I had when the oil drain plug fell out. Felt like frame flex. Wandering steering, soft mushy steering, awkward response and a extra cushy'ness to the ride.

Like @Count Arthur , I was a biker in my late 20’s and went back to motorcycling recently. I bought 5 new bikes, because I’m close to retirement and …you know… I can! ;)
One of these is a Triumph Rocket 3R: 3cyl., 2.5L, 180 hp, 166 lb-ft torque. Is it a monster? Yes! …But where modern bikes have made a lot of progress is on the electronics side: very refined throttle controls combined with all the nannies (leaning angle ABS, TC, etc.). If you’re mindful of the weight and are gentle with the throttle, the Rocket 3 is one of the easiest bikes to ride and drive around. The only thing I don’t like: I can also have (a lot of) fun …but I’m immediately 20 mph over the speed limit (I’m pretty proud to only get one ticket for speeding this year :p).

Our generation of teens had this:
250px-H2750.JPG

H2 Mach IV 750
Kawasaki had "done little" to address chassis problems, and so the bike was still prone to speed wobble: To help address the speed wobble issue, the H2 came with a friction-type steering damper, as well as a built-in frame lug to attach a hydraulic steering damper (you know that many did not put the hydraulic steering damper on it [because of the "I'm young, have quick reflexes and can handle it"] attitude). There were many negative consequences as a result.
The H-2 was comparison tested by Cycle magazine in 1973 against the Ducati 750, the Honda CB750, the Harley-Davidson Sportster 1000, the Kawasaki Z1, the Meriden Trident, and the Norton Commando 750. The competition consisted of acceleration, braking distance, and road race course lap-times. Each test was run several times including 10 attempts at a fastest road course time. The H2 was the fastest accelerating machine, posting the fastest 1/4 mile run on a drag strip. Cycle's testers were surprised that despite an uncomfortable feel and slight front wheel hop under hard braking and not giving the sensation of stopping particularly fast, it had the shortest stopping distance and highest braking G load of all the bikes, winning best in class measured by stopping power from 60 mph. On the road course, despite what had been heard and written about its ill handling, frame flexing and the supposed tendency to speed wobble exiting high speed turns, the H2 was tied for the fastest lap time with the Kawasaki Z-1 to the tenth of a second. Overall the Kawasaki H-2 750 had the lowest ET, second-highest quarter-mile speed, the fastest lap time, the strongest braking force, the highest torque and horsepower readings on the dynamometer, the highest power-to-weight ratio, the lowest price and scored by points for performance was by far the least expensive per unit displacement. Brown's assessment was that the front disc brake performed adequately, though some riders added a second front disc for more braking performance.
By 18, most of us where drag racing various highly modified bikes (but we also had been riding various motorized things since we were 8, at least where I lived).

I was downtown yesterday and @ a traffic light I saw a perfect example of a Kawasaki triple 750 2 stroke. Sounded great and was not smoking at all. Nice bike but I ow the peril that awaits. LoL.
 
A brief history of Pablo’s motorcycles… I have had several more, but these are the ones I kept for several years and which left the most of a mark in my memory:

Montesa Cota 74

1760376635779.png


A perfect bike for a kid to get started. So much fun. It could do a bit of everything (except turning itself road legal…)

Bultaco Streaker 125

1760376650201.png


…but the day I turned 16, I was riding this on the street. The handling was absolutely awesome. They even had a national race series for this bike series. I quickly discovered that as a 6+ ft tall 16 year old with a swimmer’s body I was never destined to become a motorcycle racer… :-D I credit this bike with this early discovery. Never mind I wasn’t anywhere as crazy and fast as other competitors…

Laverda 500 Montjuic

1760376664971.png


Tears streaming down my face when I look at this utter beauty that I shall miss for life. So much fun, but then again when you are 18 and love something irrationally, you put up with some temperamental quibbles here and there. I loved it. Unfortunately there was a summer when I had to hurry back to Germany, but it was storming badly - so I left it at my Dad’s house intending to pick it up asap… but my brother-in-law “borrowed” it and totaled it… unfortunately not braining himself in the process, which would have made the loss worthwhile. PS: A bit confused because I seem to remember mine was a 600cc, but all the pics I could find say "500" in the body work. Looked just like that anyhow.

BMW R45

1760376724584.png


But I have to admit the Laverda hated German winters and wet weather in general. The R45 is quite possibly the most boring bike I have owned, but own it I did, for 5 years. And to this day I have a soft spot for my trusty University companion, which featured qualities most appreciated by a student: (a) indestructible and cheap to maintain (b) soft yet torquey “power” delivery that made it great in the German weather (c) the ability to not show scratches and such much when you inevitable dropped it in the snow or even ice. I never had the heart to sell it, so after not using it for a while I gifted it to my fav little cousin (who still owns it, I think he said it has nearly 550k km on it). Only the first 170k were mine.

Honda CB1000

1760376740458.png


Hyper reliable, too - I put a lot of miles on this one travelling all over Europe with my buddies in the summer. Smooth as butter. Mine had an aftermarket top fairing and of course an aftermarket exhaust (very legal -don’t try open pipes in Germany) with a sweet sound.


Ducati Monster

1760376755376.png


What a fun bike! It was so easy to flick around, and that classic Duc V2 sound! Also had a very small top fairing on it, and the prerequisite Termignoni exhaust they didn’t’ seem to allow you to walk out of the dealership without.

BMW R1100R

1760376766526.png


When I moved to California, I knew I wanted to discover my new environment on a motorcycle, and since large distances were about to be covered, reliability was a key concern – and the R1100R never disappointed. Very fond memories of my adventures with this one. The boxer engine’s cylinders also protected my legs during a nasty collision with a deer on a foggy, very early morning up the Mendocino coast.

BMW R1100S

1760376779021.png


Actual pic of my bike here. Probably my favorite ever. Power delivery is so good it doesn’t need any traction control, and with 104 benign HP on tap it is no slouch in the twisties, and comfy on long trips. Now it is babied (I have taken fantastic loving care of it for over 20 years, looks like new).

Piaggio MP3 500

1760376792149.png


This is an amazingly practical everyday contraption and my main urban and mid-distance vehicle. Plenty of storage for my (and my cats’) needs under the seat. 500cc and 44hp don’t make this exactly a rocket, but it still accelerates faster than most cars on the road (which to me is a safety feature on a motorcycle if used judiciously). And the two wheels up front make it stop hard plus make it pretty much impossible to ever lose the front end (yes, it does incline just like a motorcycle, and watch out, because it can fall over).

Honda NX750 DCT

1760376804859.png


Also a super practical and underrated bike. Plenty fast, very balanced, storage room, agile… and while I love using a clutch, I have to admit the DCT transmission is a lot of fun and is brilliantly designed for the dynamics of a motorcycle (which I assume is not an easy engineering task). I originally bought this bike as a temporary solution while the R1100S was having its electronic wiring replaced, but have kept it. It allows me to not put more miles on my precious R1100S. :-D

2 strokes - love the smell, hate the noise. :)

I'd quite like an RD 350 though.

View attachment 482732
The street ride 2 strokes are vastly different than say a 2 stroke MX dirt bike or a pure professional enduro 2 stroke ride. The dirt bikes are much louder and peakier and make glorious noises. If you ever get the chance to try out a dirt bike 2 stroke ride go for it. It's a totally different experience and it is all about the visceral thrill and the excitement.

This is mainly because the dirtbikes have much shorter gearing and feels scary because of that, combined with the typical explosive 2T power delivery. BTW the last iteration of the street RD350 have more HP than any stock 2T dirtbike, racing or casual, maybe a CR500 or KX500 is close enough.

As I wrote a few posts back, I never feared a dirt 2-stroke. I ride them since I was a teen, started with small YZ90 all the way to YZ490 which I still got.
Respect but not fear.
It's a different kind of power.

But the Yamaha TZ750 really scared me, and it was not the first time I drove a fast street bike, all of them at the '80s was kind of scary but not at the level of that thing.
