1971 T120rv Bonneville

Looking for a little help. I have a 1971 T120RV, and no it doesn't have the Quafe 5 speed, it a factory V (5 speed) serial No GE27XXX. Those in the know recognize that number as last of the production run for 1971.

I have found plenty of anecdotal references to the 200 factory built 5 speeds made for the US market prior to the 1972 release. the key difference on these models is 1st and 5th gear ratios are the same as 1st and 4th on the 1971 4 speed. 1972 they changed 5th.

I am looking for a Triumph confirmation that this is true. anyone else know about these?

Thanks in advance.

 

Hey just saw your reply. I'd be happy to help if I can. my 1971 has been in the family for over 40 years and has been a great ride!

 

no sorry that is the Quafe I mentioned above. from the same article.

" Late in 1971, an optional 5-speed Quaife gearbox became available, originally an aftermarket item adopted by the factory race team. It would be next year before they would designate these 5-speed bikes differently, with a "V" suffix (ie: T120V). Gearing was lowered with a 47-tooth rear sprocket, in the interest of acceleration."

Check the T120RV in this page,

• T120RV - The 5-speed is generally considered to have been available—and was advertised as such—starting in 1972 with the T120V. However, a small pre-production run of 5-speeds were made in June 1971 only, and sold as '71 models. They were externally identical to their '71 T120R 4-speed counterparts, and did not carry any "V" decals such as the 1972 5-speeds displayed on their side panels. They were factory (not dealer) modified T120R models, so their engines/frames/and titles are designated T120RV,with the V being stamped separately when the transmissions were installed. These early factory Triumph 5-speeds are not to be confused with the Quaife 5-speeds that were listed as stocked for sale by Triumph dealers in 1970 to qualify for AMA purposes (the parts "had to be available from Triumph"). The first and final T120RV ratios in 1971 were the same as the 4-speed model, making it a matter of closer ratios, unlike later 5-speeds. These 5-Speeds were not advertised, were not available as an option, and could not be ordered—as the few manufactured were simply distributed individually to selected Triumph dealers and sold by word of mouth.
