Ride Engineering no longer makes the rear brake master cylinder extension for the cr250 two stroke and I can't find one anywhere.

I have found this kit from kite, link below.
I've called/emailed kite, and crf's only and have gotten no response.
Anyone know if this will fill the 04 250 two stroke. Thanks

The cap for the rear master cylinder hasn't changed since 2004, so an extension for any of the newer bikes should still work.

Thanks.

Got a response and the kite kit will work for anyone interested.

Do those extenders actually work for keeping brakes cooler?

2nd last gen cr250.
Boiled both stock setups.
Ride engineering cured the first one, have the kite ordered for this one.

I"m also old, slow and drag the rear to steer in tight stuff.

I've never had a problem boiling over any of the rear brake systems on any of the cr's that I have owned, so long as I was using good brake fluid, and I'm really hard on the rear braking system. I use Motul's RBF 660 or the 600 fluid, and have never had a problem out of the rear brake system that I didn't cause.

You ride KTM's right? There is an additional factor to consider with KTM's, the separate pedal position adjuster. This creates a different scenario when it comes to overheating the rear brake since this adjuster essentially applies pre-action pressure to the pedal. It takes up some of the throw before you get to the bite point, potentially making overheating more likely. It's basically the same as someone resting their foot on the pedal and dragging the brake.

There is a fine balance on how much to fill the reservoir to prevent a dynamic overfilled condition when the brakes get hot and the fluid expands. The small size of the reservoir makes this pretty tricky. So, in that sense, the reservoir extender gives you more room to play with to prevent a dynamic overfill condition.

Yup, chased a brake fade problem forever on my main runner. I settled with putting more a little more freeplay than recommended in the lever by adjusting the lock nut on the clevis after getting my pedal height dialed with the system you mentioned. Use RBF600 and put a Fasst Co. spring kit on (Nice little piece).

All has been good! Was always curious on those extenders, always seemed like more of a gimmick but your explanation makes sense!
