There's a slim chance I might be getting a 2005 280. I know already it needs a new top end which I've found for $600 for replated cylinder/piston kit. My question is can a Honda CR250 crank fit this engine? I know that it will fit the 250/300 enduros. By the way, if I do end up with this bike it will be the very first trials bike I've ever owned. I've had Jap dirt and street bikes. English dirt bikes, KTM's and ATKs of various displacements. I almost bought a Scorpa 250 back in 07 but was tempted to the dark side and bought a 1995 KTM 550mxc 2-smoke instead. I started riding in the 60's so yeah I'm OLD!!
