1971 TRIUMPH 750 TRIPLE, ONE OWNER since new, until two years ago when I bought the bike. Have put two miles on bike testing it. ONLY 3635 MILES. These are original miles. NOT 'miles since a restoration'. This bike is original. Bike was running when I put in storage two years ago. This bike would be phenomenal for one of three things, either: 1. Great base for a museum piece. 2. A transformed machine. If someone wanted a solid base to build a killer modified Triumph, original but with performance parts, they'd want to start with a foundation such as this. 3. A wicked fun ride. Matching serial numbers on engine and frame. BIKE HAS BEEN WELL CARED FOR SINCE NEW. ORIGINAL PAINT, GREAT PATINA. BIKE HAS BEEN STORED INDOORS FOR 40 YEARS AS A STATIC DISPLAY. Has been running, but not since two years ago. Driven 2 miles since purchased. I have four other bikes, 3 vintage Triumphs and a Norton.

 http://www.classic-british-motorcycles.com/1971-triumph-trident.html THE 1971 TRIUMPH TRIDENT EVOLVESAfter 2 model years since it’s introduction in 1969, the novel Trident triple continued to evolve slowly, both mechanically and stylistically. On the styling front, the restyled 1971 Triumph Trident benefited from all the new cycle gear introduced on the also new and it’s stablemate, the 1971 TR6.Triumph and BSA had just spent a pile of cash redesigning the big 650 Twins, and all this shiny new hardware naturally percolated down (or up, depending upon how you look at it) to the Trident. Just as the 1970 Triumph Trident bore a strong family resemblance to the 1970 Bonneville, this new 1971 Triumph Trident also looked very much like the 1971 Bonneville and TR6 twins.STYLING THE 1971 TRIUMPH TRIDENTMost obvious right off are the conical brake hubs front and rear. While these hubs look exotic, and happen to be among my personal favorite, from a purely esthetic point of view, they never stopped as well as the 8-inch full-width TLS (Twin Leading Shoe) front brake and 7-inch SLS (Single Leading Shoe) rear brake they replaced. Those brakes came straight off the 1968-to-1970 Triumph Bonneville that were used on the 1969 and1970 Tridents, and they did a good job of hauling down the heavier, more powerful Trident and BSA Rocket 3. Unfortunately, the same cannot be said for the conical hubs that arrived in 1971. But they looked good, and sometimes that’s good enough. The 1971 Triumph Trident also received the new front forks with exposed stanchions and aluminum sliders, and those slender tapered megaphone mufflers from the 1971 Triumph Bonneville. A new tank, seat, fenders, head & tail lights, and miscellaneous cycle gear, also from the Triumph twins completed the package. In fact, the only piece of “eye candy” (ie: bodywork) on the whole bike that didn’t come straight from the twins are the side covers. And as you can see, the end result was a handsome motorcycle by anyone’s standards.MECHANICAL CHANGES ON THE 1971 TRIUMPH TRIDENTThe full raft of 1971 Bonneville/TR6/BSA A65 cycle gear and hardware were applied to the T150 Trident and BSA Rocket 3 and this necessitated a long list of engineering changes and upgrades, some major, some incredibly small, but required nonetheless. The new front forks reduced the Triumph Triple’s wheelbase by a full inch, down to 57 inches. The stylish new side covers had “Trident” transfers (decals) rather than screw-on emblems as before, and no longer covered the air cleaners. The new flat “pancake” headlight had its own rotary switch plus warning lights turn signal indicators, along with the main ignition/light switch. Grab rail, fender mounts, headlight mounts, everything was changed. And after they were all done, they big Triumph triple had lost 8 pounds. Warranty claims resulting from reliability issues (ie: engines blowing up when you ran the crap out of them) triggered a mild detuning of the engine including changing the carburetor slides from 3 to 3-1/2, and a drop in compression ratio to 9:1. 1971 TRIUMPH TRIDENT UNLIKED AT HOMEWhen they did leak out into the British home market, many Brits disliked them because of their poor fuel economy and small fuel tank, along with their sparse fenders (mudguards in British-speak) and weak brakes. Oh well, the whole re-styling effort was intended for the all-important U.S. market anyway. And again, it succeeded in that department. The 1971 Triumph Trident is a looker.
