My RM400N had a 15t on the front when i first got the bike and unless your racing "Finke" you dont need that tall a gearing.

07 RM250 - Finke setup 15/44..

Thanks Toolboy was thinking of running 15/50 or 15/48 for dirttrack (broadford) but was not sure if a 15 or16 would fit without hitting the swingarm buffer
