After getting my dd1200 home and getting to ride it I noticed that for a modern bike the clutch pull is heavy in fact my friends new Harley is much lighter.I had the same thing on my 1999 Bandit 1200 and fixed it by swapping the master cylinder with a nissin radial master cylinder with a 19mm piston.The bandits clutch went from stiff to being able to pull it easily with one finger since the dd1200 was a new bike but a 2011 and who knows how old the fluid in the clutch was and needed changing I thought I'd swap the nissin on my bandit with the dd1200 and get a nice light clutch pull,WRONG it made the clutch pull harder no HARDER you could pull it but it but you wouldn't want to get in heavy traffic with it.I know it has something to do with the dd1200s clutches piston size and the ratio between it and the master cylinder.If anybody reading this has more information about this and what size master cylinder would work better and be willing to share it I'd love to try again.You can pick up a master cylinder off ebay for cheap and a nice light clutch would make the dd1200 even more fun..

Locky you are indeed correct...the DD1200 has quite a stiff clutch compared to other bikes. I have the shorty levers which make it slghtly stiffer still, and I have to use 3 fingers all the time. I wish there was a simple and cheap solution to this!

Sumptin going on here, doesn't make sense. Mine is as light as, and very quick to use. Like a motorcross clutch. Zviadi also is looking at the clutch. Is it different models for different countries?
