Front brake bore size?

theredsox · June 20th, 2011, 12:30 PM

Hi everyone. I'm buying a custom lever system for my 2010 Ninja 250r because of a disability I have. I will have both the front brake and clutch lever on the right side of the bike. The company I'm trying to order the parts from today asked me a couple specific questions. Unfortunately the motorcycle shop I bought my bike from and currently has my bike, is closed on Mondays. I hope someone here might know/verify the answer to these.

Q: Bore size of front brake master cylinder?
A: 62.0 x 41.2mm

Q: Is it a hydraulic clutch?
A: No, cable-actuated

Q: Assuming it is a cable clutch; is it nipple or lasso?
A: From the 'DIY Replacing the clutch cable' thread for changing a clutch cable, doesn't look like anything is lasso'd so going to say nipple

Q: Assuming it is a cable clutch; what is the distance between the lever pivot point and center of nipple/lasso?
A: Again looking at the DIY, there was a convenient picture of the lever with a ruler by it. It looks like 20-30 mm.

Thank you for the help.

I think I found all the info I needed from the 'DIY Replacing the clutch cable' thread. Would be comforting to have confirmation though as I currently don't have my 2010 ninja yet to look at or the manual. Spending $1500 and getting the part from England, so really want to make sure it is right the first time.

I didnt see it in the 250r manual...... But, stock master cylinder pistons are like 14mm & 16mm.

Thanks HKr1. The 62 x 41.2 I saw is probably engine cylinder and not what I want. 14 and 16mm sounds realistic.
