I’m trying to achieve a final drive of 4.9. I currently have two choices:
GP200 box with 47 and 19 front sprocket 4.95
SX200 box with 47 and 15 front sprocket 4.92
I’ve currently got a standard GP200 set up so would only need to change the front sprocket and get a longer chain. Just a bit concerned as this will mean the sprockets running faster and supposedly leads to early wear and tare. Would I better going down the SX200 route. Anyone have experience of the GP200 set up?
Thoughts please

I’ve ran the Italian gp set up on my gp for15 years, not a problem

Is that with a 19 tooth front sprocket?
