1970 Triumph Motorcycles Bonneville

The 1970 Triumph Bonneville really does represent the best of what Triumph motorcycles had to offer at that point. The 1970 Triumph Bonneville T120 was not only the high water mark in Triumph 650 development, and the year that most people favor as 'the best Triumph Bonneville ever built', it was also the last year before the dreaded Oil-in-Frame bikes arrived. The 1970 Triumph Bonneville T120 650 probably really is the best one ever built, its certainly one of the prettiest. They run great, they're fast, and they handle fantastic and stop well. As classic British motorcycles go, this is just about as good as it gets. Model designations remain unchanged: T120R was the Road or street version with down pipes; and T120C was the off-road/trail/street scrambler. 1970 Triumph Bonneville model year changes started with Engine #JD24849. Crankcase ventilation, always a problem with vertical twins where both pistons rise & fall together, was revised & the timed breather eliminated. Now the engine breathed through the primary chain case, via 3 holes drilled between, then out a vent tube behind the clutch & out a rubber hose that ran out the back, along the left edge of the fender. This system yielded a second benefit by keeping the primary always well oiled, but allowing any excess oil to run back into the engine through the holes. A chromed grab rail was welded on to the rear fender mounting loop and the seat was lowered slightly. The 1970 Triumph Bonneville 650 really is a gorgeous bike, and one of the finest, if not THE finest, Classic British Motorcycle in the world. The Triumph Bonneville certainly would be on a very short list indeed, and as Bonneville’s go, 1970 was probably the best. It's certainly one of the most sought-after today, by collectors & enthusiasts alike. They're not only drop-dead gorgeous machines with loads of history, but they're fast & they handle great, even by today's standards.
