Hi all,

I work with the owner here at ASV Inventions and we are having no luck getting parts to R&D a new brake lever for the R7. All of our dealers and suppliers are out of stock till Mid-next year. We need a brake lever and the brake master cylinder for about 2-3 weeks. In exchange, you will give you a full brake and clutch set for free in any color combo you like. Keep in mind you probably wont be able to ride while we are developing the lever.

We are based out of Huntington Beach, California and we would prefer someone local but are also open to someone mailing us parts.

I’d be happy to - I’m up in the Bay Area. I’ve sent parts to Woodcraft (rearsets and bodywork) and would love to do the same with you guys.

I can drop mine off, perhaps today, I'm local. I replaced the master, partly due to availability of a spare lever, so it's sitting on the shelf now so that should work fine for you and me.

I look forward to seeing the outcome! There need to be more adjustable brake options.

I dropped it off Friday. Hopefully it's an easy production change and setup from an existing lever spec. Or however they do it.

If possible, just let us know which is the typical replacement type for the brake lever...

Since it is a brand new master, that is a hard find and the stock lever was not available from Yamaha. It is a bit different than the normal RCS line, you can't just use a Brembo 19 or similar lever. Maybe they have one, that answer may need to come from Brembo themselves.

Okay, interesting to learn that Yamaha went to a new master on a budget bike. Instead of relying on existing designs what hey use since decades.

Do you remember the nominal piston diameter of the master?

It has been measured or spec by someone on here to be 16mm.

My guess is they wanted to go newfangled racing technology and Brembo had this in the works. A complete wild ass guess.

I purchased the C5 shorty Levers that were advertised for the brembo master….. They are awesome levers! unfortunately the brake lever did not fit & it doesn’t activate the brake light since it is a racing lever…. I emailed them and they actually called me personally to offer a refund which was really cool of them. I am anxiously awaiting the replacement since the clutch lever worked perfectly, would love to have the matching front brake lever…. KEEP US POSTED ASV!!!!!

You could use a pressure switch to activate the brake light perhaps. I do not have the stock master right now to look at the setup to see about potential clearance issues.

I haven’t used one before, I will have to look it up. If it works I think that would solve the problem with the asv race lever - I think it kinda fit, but had a little bit of a clearance issue if I remember correctly…

I switched to a Brembo 19RCS master and running a double banjo from it (separate brake lines) it definitely has clearance issues with the stock risers being in so tight. Thank goodness for folding levers! It's not bad, I just had not thought of it being an issue prior to installation.

I like the stock bar position, I don't think I want to go farther forward just to provide for more clearance.

I did a little bit of tinkering around and have a temporary fit for my ASV C5 shorty brake lever… the clutch lever fits like a glove…. The front brake needed a spacer for the pivot bolt and I am playing with a couple ideas for the brake light switch…. I might do a little 3d printing this weekend to get it finalized… but for now it works until ASV gets the lever out to us!!
