Big Red Gear Reduction
The Big Red 700 side-by-side uses the same engine as the Rincon. The Big Red is geared lower, so you can swap the gears under the rear case to Big Red gears getting a gear reduction to run bigger tires.
I did the BRGR and replaced those redesigned gears that are grinding on you on my buddy's 06 last year. No more grinding in gear, and he can do a wheelie from a dead stop with the BRGR. His top speed did drop quite a bit though.
What is his top speed after doing the mod?
