Any motorcyclists on this forum?

They booted out the Indian FTR750 too. :rolleyes:

Possible solution is for Harley and Indian to make new versions available to folks to purchase at the local dealers - if that is what the rule makers require. Continue to "play the game" so they can "stay in the game".
 
uh, you realize that's a real bike, not a poster, right?
Yes, it's a picture of a bike.
I have friends that raced the Laverda's back in the day.
And Evel quite using them in 1970.
I got my first bike in 1971 (when I was 14), a new Honda CL 175.
I've been some sort of a mechanic/racing gear fabricator/Engine and chassis modification person ever since before that with Go Karts & Mini Bikes & off road vehicles.
 
A bit of a difference here: Jim Hall's Chaparrals could not be purchased through your local car dealer and driven on the street (although a few managed to get a Lola or a McLaren from those days registered for the street).
Youtube has a video or two on Jim Hall and the Chaparrals. Jim actually is explaining things in the video. The video is unbelievably interesting and shows how some guys are just ahead of their time. He invented so much in racing it is mind boggling. Also, he did it with old, old tech and lots of hard work.

1970 in essentially a car that you could buy from the local Dodge Dealership:
(which there seems to be some evidence of it being able to run 236 MPH in a straight line & had actually been "de-tuned" for NASCAR):

The 200 MPH Dodge

by Tom Jensen April 18, 2023


Buddy Baker’s record-breaking Dodge Charger Daytona is now on display in the NASCAR Hall of Fame as part of our “NASCAR 75: Moments and Memories” exhibit.

One of the six featured cars in the NASCAR Hall of Fame’s newest Great Hall exhibit, “NASCAR 75: Moments and Memories” is a very special 1969 Dodge Charger Daytona. Known to Chrysler Corp. engineers as serial No. DC-93, this is the first car to lap a closed course at more than 200 miles per hour.

On March 24, 1970, during testing at Alabama International Motor Speedway (now Talladega Superspeedway), Buddy Baker (NASCAR Hall of Fame Class of 2020) turned a lap of 200.447 mph in this high-winged, swooped-nosed Dodge. Baker’s lap not only broke the once-unthinkable 200-mph barrier, but it was also more than 30 mph faster than the pole speed for the 1970 Indianapolis 500.

Now owned by Scott Borchetta, DC-93 was the subject of a meticulous, multi-year restoration by Hall of Famer Ray Evernham (Class of 2018) and his team of craftsman. The NASCAR Hall of Fame is extremely grateful to both men for allowing us to display this priceless piece of racing history.

DC-93 has a long and colorful history. It began life as a 1969 Dodge Charger 500 that was used as a magazine test car on the West Coast. Unfortunately, it was stolen, stripped of many of its parts and later found perched on cement blocks in the Watts section of Los Angeles.

Chrysler officials reclaimed the stolen car and shipped it out for repair. Nichels Engineering in Indiana rebuilt the hulk and made it into a proper NASCAR stock car, intended to be used for research and development. Fitted with the Daytona’s rear wing and special aerodynamic nose, DC-93 was tested on the 4.75-mile oval at Chrysler’s Chelsea Proving Grounds in Michigan, where it purportedly topped 205 mph in the summer of 1969.

The chassis for this car was also raced at NASCAR superspeedway events by a variety of different drivers, including Hall of Famers Bobby Allison (Class of 2011) and Bobby Isaac (Class of 2016), as well as Dan Gurney, Paul Goldsmith and Charlie Glotzbach. But it’s main claim to fame was Baker’s barrier-smashing 200 mph run at Talladega.

Baker, characteristically, was humble after running his record-setting lap. “Gosh, it’s the best feeling I’ve had in a long, long time,” said Baker. “This is something that no one can ever take away from you, being the first guy to run 200 mph on a closed-course circuit.”

Talladega was built by NASCAR founder and Hall of Famer William H.G. France (2010) in part to be a track where speed records would be set. That’s why the track is the longest oval in the sport, and why it was banked 33 degrees in the corners, something Baker said he didn’t even notice at speed.

“Well, believe me, when you’re running 200 (mph), it feels just like it’s flat, because it takes every bit of the banking to run this speed,” said Baker. “We’re just tickled to death to be able to come down here and break the record.”

France himself was on hand to witness Baker’s record-setting run, as was NASCAR’s chief timer and scorer, Joe Epton, who brought his timing equipment from Atlanta International Raceway (now Atlanta Motor Speedway), where a NASCAR Grand National Series race had been rained out the previous weekend. If Baker was going to set the record, NASCAR wanted to make sure it could certify the mark. The sanctioning body even inspected Baker’s Dodge prior to the test to ensure it was legal.

The morning began wet, but the weather improved and the track dried by early afternoon, allowing the test to proceed. Baker patiently brought his Dodge Daytona up to speed during the full day of testing, eclipsing the 200 mph mark with a lap of 200.096 mph on his 30th circuit around Talladega. Four laps later, Baker hit 200.447 mph, which became the track record.

When Buddy Baker broke the 200-mph barrier, his car carried No. 88 on the right-side door, but no number on the left side, so that’s how Ray Evernham and his crew restored the car – exactly as it set the record in 1970. Photo courtesy of Cassie Townsend
Getting the record run certified by NASCAR played a key part in the story, as Baker would tell The Huntsville (Alabama) Times in a 2010 interview. “There’s a lot of people say they climbed Mt. Everest on the backside and nobody saw it,” Baker told the newspaper. “To be the first official (lap above 200 mph), that’s what matters to me.”

Baker was accompanied to his record-setting Talladega run by a cadre of Dodge engineers, who fine-tuned the winged Dodge Daytona as the day went on, trying to coax ever more speed out of it. In a 2001 interview, Baker recalled a conversation he had with Dodge personnel on the day he eclipsed the 200-mph mark.

“After we broke the 200-mph barrier, I said: ‘Let's go to it and really set 'em a record,’” Baker recalled telling Dodge officials. “They said the next barrier is at 300 mph and asked me, ‘Do you want to break that one?’ I said, ‘No. Scratch my name off that trophy.’”

That day in Talladega turned out to be one that would stick with Baker for the rest of his racing career, an important accomplishment in the sport’s history and one that no one else could claim. Other folks would eventually go faster, but Baker was the first to eclipse the 200-mph mark.

“Dodge picked me to run the first official 200 mph lap at Talladega,” Baker said in the book “Flat Out and Half Turned Over – Tales from Pit Road with Buddy Baker.” “We had all run 200 mph before, but not officially. When they did pick me to be the one, there was a lot of bellyaching from the rest of the guys driving Dodges. We got a lot of press. It wasn't a big deal for me back then, but it became a big part of my life.”

Just think what might have happened if NASCAR had not banned the aero cars in the early 1970's.
How much faster & better would we have advanced in automotive, military and the space industries? As well as many others (for materials like carbon fiber, Kevlar, metal alloys for strength & lightness, etc, too).
That was a major mistake IMHO.
 
I'm torn on old ducati's. It seems they get special treatment for competing in superbike with retarded .. er, i mean twin cylinder engines. They can race bigger displacement because the design is so dumb. Doesn't seem fair.
Never been a more boring engine to either ride, or just listen to as a bumblebee clone Japanese Inline 4 BLAH
Send them all to the crusher. :p

LMAO... I rode a 750 Honda with bore kit, open header, bigger carbs and no intake box and man alive did it howl out on the mountain passes. (Shifting gears with exhaust note sound.) WHaaaaaaaaaaaaa whhaaaaaaaaaaaaaaaaaaaa whaaaaaaaaaaaa... LoL. I loved ripping through the gears at night. No bumble bee sound there.

We used to buy up the old Honda's and take em to the swap-meets:p.
Then charge guys $1 or 2 a swing with a 10# sledgehammer to beat them into the ground.
We'd make a bundle every time. LOL

Savages..! LOL... I can see it too. A crankcase hit would be worth $5 and a gas tank $10 all other parts a dollar or two. :D
 
Laverda
In the early to mid 70's other 'high speed' "street" bikes could not touch these:
The SF evolved to include disc brakes and cast alloy wheels. Developed from the 750S road bike was the 750 SFC (super freni competizione), a half-faired racer that was developed to win endurance events like the Oss 24 hours, Barcelona 24 hours and the Bol D'Or at Le Mans. This it did, often placed first, second and third in the same race, and dominating the international endurance race circuit in 1971.[2] Distinguished by its characteristic orange paint which would become the company's race department colour, its smooth aerodynamic fairing and upswept exhaust, the SFC was Laverda's flagship product and best advertisement, flaunting pedigree and the message of durability, quality, and exclusivity. The SFC "Series 15,000" was featured in the Guggenheim Museum in New York's 1999 exhibit The Art of the Motorcycle as one of the most iconic bikes of the 1970s.
They showed Ducati the way!
For some USA folks that do not know: Many of the first bikes were produced for the American market under the brand "American Eagle", which were imported to the US from 1968 until 1969 by Jack McCormack, and
were used by stunt rider Evel Knievel until 1970.

My pride as an 18 year old was a used Laverda Montjuic 600. Loved that bike, even though it had an electrical system that reliably predicted rain a day in advance or so. Also owned 2 Ducatis, the first one also had a temperamental electrical system, the second one (mid 90s) was awesome.

Also rode the big Laverda Jota. I remember the clutch being designed for werewolf hand-paw strength. :)

But I have to say the most intoxicating engine sound ever to me was a 6 cyl Honda CBX. And the Valkyrie 6 cyl was also pretty cool (albeit heavy as a mother_..).

The Benelli Sei is a series of motorcycles that were produced by Italian manufacturer Benelli, and masterminded by automotive designer Alejandro de Tomaso, from 1973 to 1989.[2] Two models were made, with 750 and 900 cc displacement. The 750 was the first production motorcycle with a six-cylinder engine.

Benelli 750 Sei​

[edit]
The Benelli 750 Sei was the first production motorcycle with a 6-cylinder engine and had two model releases.[3][4] De Tomaso intended it to become Italy's premier sporting motorcycle and wanted it badged as a Moto Guzzi. On its launch, it received tremendous publicity overshadowing all other Italian bikes of that year. It started the trend of angular designed motorcycles moving away from traditional round forms.[5]
The engine was based on the four-cylinder Honda CB500, but with two extra cylinders.[6][7] The cylinder head fins of the Sei were squared off to provide a cosmetic individuality, but otherwise the engine is in most respects obviously derived from the Honda. The "angular, bold design" was by Carrozzeria Ghia.[8] It produced 76 bhp (57 kW) at 9,000 rpm, had a top speed of around 127 mph (204 km/h) and was one of the smoothest European tourers.[1][9]
Despite the extra cylinders, the Sei's width was kept to a minimum by siting the alternator (which, on the Honda, is at the left-hand end of the crankshaft) behind the cylinders. Cooling was improved by having air passages between the cylinders; the Sei had three Dell'Orto VHB 24 mm carburetors (the Honda CB 500 had four, for four cylinders).[7] The vehicle appeared to reviewers as heavy and cumbersome but handled surprisingly well, and had a unique signature exhaust note from its six mufflers.[10]
Production Frame numbers started at 5000.
Production figures were as follows ;

The Benelli Sei was an utter wet dream when I saw a few. I was too young and too cashless to even remotely contemplate one - as with all six cyls they had a reputation for very expensive maintenance... odd because they were known to basically be 1.5x Honda 4s put together.

See I used to go for free to the local HD dealer and see whether they were using plastic oil catch pans or the ubiquitous pie pan to catch oil under each new Harley on the showroom floor. Then get on my Honda or Yamaha and ride home. My Vance and Hines 4 into 1 was no bumble bee either. I can understand why guys would be willing to pay to take out their frustrations.
 
Just curious. I don't believe I've ever run into motorcycle fanatics on audio forums, haha!
