It has only 15 minutes break in on motor , 6 speed watercooled with pipe and mount with a paddle shifter mechanism for any kart . Motor is Nickasi coated , knife rod , with 250 ROTAX piston, yes the tranny can be removed but why would you. Also it has TM 40 mm side cab, also electronic tach rpm in 22,000 rpm over 65 hp.
