Starting with the 1970 Triumph TR6, the rear chain oiling system, essentially an adjustable 'oil leak' fed by the oil tank, was eliminated because...why else?...it leaked! It would leave puddles on the ground & there were too many of them already. The front fender (mudguard) got a new bottom stay & the rear fender was modified to accepted the "D"-section breather hose which ran along its left side.

The rear grabrail was now integral with the rear fender stay. A new seat pan lowered seat height. The speedometer was changed again to a SSM/00 & the tachometer (rev counter) to an RSM 3003/13.
