+Erik Lemos my mate has a 2009 suzuki gsxr1000 has 88,000km on it and he doesnt do any maintenance on it. he did 45,000km without a oil change never had a valve clearance only service it has had was at 10,000km. its in the shop getting a lot of work done now as clutch is fucked gears are badly worn. any bike will do for ages even longer if maintained correctly.

Damn 45000km without a oil change is insane, i´ll buy a gsxr 600 2008 and the bike have 40000 km, and the full service history, all done in suzuki, so yeah i dont mind the 40000 km if the bike was maintained correctly Adjriannickelodeon had 90000km on his 2009 r1 and never had a single problem
