Bike year: 2013
model: fantic tr250es (90% GG, if we're being honest)
mods: Jetting (N3CJ needle, 40pilot, 178main)
Gearing: 12/48
Top speed: 120kmh-ish?
what kind of riding do you do: Anything from sand whoops to hard enduro and enduro cross.
Same as 13/52. It was easier and cheaper to change the front sprocket, and less difference in chain adjustment from stock gearing (13/48). Nice and snappy.
