August 10, 20197 yr Hi are GAS GAS and TRS engines the same, as on the S3 website they say that some engine parts fit both bikes thanks
August 11, 20197 yr Cylinder head is different as the TRS has a bleed valve in the cylinder head. I think piston may fit ?
August 11, 20197 yr Huski 22 hours ago, huski said: Top end is the same but that's all That is not true Huski. The cylinders are not the same, the cylinder heads are not the same. The base gaskets are not the same, Only some of the pistons and little end bearings are interchangeable. The friction plates in the clutch are the same dimensions, but the steels are not. Very very few parts the same in both motors.

So for the sake of conjecture if I wanted to renew the clutch on my TRS Gold I could order the Kevlar plates the new gasgas use theoretically?
