I traded my 2011 busa for a 2009 m109r. It was the worst mistake i ever made. The 9r was a good bike but it aint no busa and it does have some issues suzuki ignores. The clutch shudder is a real issue. There are some self mods that help but none actually fix the problem. The oil puking is another issue as well. There are several different methods of changing oil that supposedly work but it all depends on who you talk to. Also the front tire on the 9r is to small for the weight of that machine. It is very unstable under heavy braking. There are a ton of mods for the 9 but sadly there really is no fix for the driveshaft. I didnt like the shafts at all...found myself researching to find a belt drive set up. Rotex was supposedly making a super charger for it but i havent heard much on it. So i sold the bike. I have been scouting for another busa but i want a gen 1. Miss my viperblue gen 1
