Master Cylinder

[Señor Willy]

Need a master cylinder for my mastiff.
Would this be up to the job I wonder or should I avoid?
Anything would be better than the one one the bike.

Brake masters are pretty universal. I would just check your stock one to see if there is a size marking on it and try and get one that is the same. I would recommend a newer used brembo or nissin master, both are great. I imagine a 12.7mm or 13mm would be around the size for a single 4 piston caliper: that is what was on my Skorpion. I went to a 14mm brembo radial master off of a 2015 ducati multstrada and it made a huge difference in brake feel. I don't suggest that for a bike that going to be taken off road: having the integrated reservoir is good for crashes.

Hi jpmsteadi.
I was going to buy this as I've seen it recommended on here before as a straight swap but it's. not available.

really just about any master should be pretty much plug and play. I don't know about mirror mounts or the like, but thats about the biggest thing that would be annoying. I would try something like this:

Or something of the like. 12-14mm axial brake master off something relatively modern, ideally something slightly nicer of a brand too (something like KTM is more likely to have nicer components than a low cost honda or yamaha. I would use the opportunity to upgrade to something really nice like a radial master off of a ducati or the like, but its possible that will make things harder in terms of fitting the remote reservoir or the like.

Would the mz brake light wires plug straight into one of those?

kaw klr 650 and kymco scooters appear to use similar items

look at a duke in a ktm dealer shop

there is a switch on ktm unit may have to solder wires to its tabs or may just plug in

i will look at a duke sat morning a dealer an see

my traveller is using a Saxon tour(rotax) clutch cable with some odds and pieces
form BMW and a Cannondale lever to sort out my no clutch cable problem

if they made it it can be fixed
above does not apply to fords and Chevy

Just bought this one for KTM so hopefully works out.

As generally stated on previous posts, just get one with the same diameter piston as the original and you can't go far wrong. Whenever I need a master cylinder I look on eBay for a Nissin, common on modern Japanese bikes. I know you can get new Chinese copies for nowt but a genuine second hand Nissin is a better option in my opinion, your life relies on it !! I've used used Nissin master cylinders on a Norton Commando renovation and to replace a MZ master cylinder on my 500R.
If anybody knows the difference between a master cylinder on an abs system and the same bike non abs then I would like to know.
Any master cylinder whisperers out there?
