There are no displacement restrictions in the vet class. As I am no longer a spring chicken, the vet class suits me perfectly. I normally ride a 250, because 125s just don't have enough "ooomph" for me, but I really love the light weight of 125s. That's the reason I'm so interested in the 200SX. 125 class weight, but nearly the power and torque of a 250. Seems like a dream come true to me.Originally posted by viking20
the 200 is too light to run in the 250 class..........
Yep,and an extra chain in the airbox for the morning check....... ;)Originally posted by marcusgunby
viking do you remember when they used to fill the frame tubes with lead on the GP bikes to get past the weight limits??
What makes it so difficult? Is the stroke different? If so, that just means swapping the crank along with the cylinder, right? Or are there substantial differences in the cases?Originally posted by marcusgunby
No its a very hard conversion.
