	The '''TR2''' was a production roadracer produced by [[Yamaha]]. It is a [[two stroke]] two cylinder engine. The 350cc TR2 of 1969 was where horizontally split ~~crankcases~~ made their debut on a production racing Yamaha. Porting design was nothing to write home about and with windows cut into the rear of the pistons, cracks were common and a close eye had to be kept on tolerances and piston condition.

	As with all 2 stroke roadracers, reliability and performance only come with detailed attention to cranks, timing and piston ring replacement, plus of course all the other things which go together, the TR2 was no exception. The TR2 shared the same replica RD56 frame as the TD2 and featured horizontally split cases 3 years before the 250.
