The only 1970 Bonneville 750 all original Triumph still in Existence - 894 original miles. Original Owner. Rare bike only 211 of these bikes were made and approved for AMA competition in 1970. This is the only one that did not go into competition. The other 210 were stripped down and put into racing. American Motorcycle Heritage Foundation researched this motorcycle & provided letter of authentication.

    Nice bike! I just acquired a triumph T120R frame and a custom orange painted dual gas tank, already had a larger custom painted faded orange to red tank from the 50s.

    This isn't a 750! Triumph didn't make a 750 Bonney until later, when they went with oil in frame. I owned and rode several of these pre-71 machines. Great memories.

    The 1970 RTs were the "consumer" requirement and that made the 750 Triumph Twin a "Stock" bike. And all the racers then had to be derived from stock bikes. Any 650 could have been legally raced when the 750 displacement rule went into effect, OHV or Flathead. But, since Triumph didn't then offer a 750 to the public, they rushed to get one out, and AMA required that 200 be sold to the public to qualify as a "production" bike. That's why you saw so many older Triumphs, particularly the 65 and earlier bikes, in racing. The early bikes had deraked frames, compared to the 66 and later bikes, which made them handle better in Flattrack and TT races. Check your information Adam - this is the only all stock one still in existence. Here is a link showing copies of the original letters Triumph sent out regarding this experimental bike. http://triumphbonneville120.co.uk/1970-t120rt.php

    You want to be careful about claiming your's is the "only". I have an original 750RT also, still running on it's original pistons. I saw another one on eBay six months ago. It had the original Routt pistons too. Every other one I've ever seen has been fitted with aftermarket low-compression pistons.
    It's the Routt pistons that are critical, because they are the only components that cannot be replaced or faked.
    I think there are about 50 out of 204 of these 750RT's that are accounted for. That leaves about 150 of them that are still missing.
