Since 600cc cylinders are slightly taller than a 500cc cylinder, the cylinder heads will be positioned further out on an R60 and R60/2. This means the exhaustpipe must have a different angle to reach the same position along the frame.
The R60, R60/2 exhaust pipes we supply are marked with a “6” on the crosspiece for the balance pipe. See photo. The absence of this marking does not automatically mean that it is an R50, R50/2 exhaust pipe: there are several manufacturers and they do not use this marking. Measuring the angle of the exhaust pipe can determine whether it is a 500 cc or 600cc exhaust pipe: a 600cc exhaust pipe has an angle of approximately 70 degrees. The angle of a 500cc exhaust pipe is approximately 75 degrees.
Please note: there is a supplier who supplies the same set of exhaust pipes for both the 500 and 600cc models. The above mentioned 70 and 75 degree angles will not apply here.
