2015 brake options

23 posts in this topic

I was pretty happy with the brakes on the 450 until I rode a friends new KX450. 

 

Any options like a steel braided line or different pads before going to an oversize rotor?

Kx has a 270 mm rotor stock. Just buy a rotor

Yeah I believe the Yamaha is 260. I'm just seeing if there's anything besides a new rotor to make em better. I know on my street bikes pads made a big difference.

Stock yam pads are real good IMO. A line won't do much except for it fading.

You dont need a big rotor upfront just get a Tusk steelbraided brake line off rocky mount. Its a rebaged galfer and even says galfer on it. If you bleed it good with the steel braided line it will feel as good if not better than just buying a oversize rotor that is 10-20mm bigger than stock.

Why not oversized? That's usually one of the negatives about Yamaha 's and it's easy to fix. I put a tusk 270mm on my 14 and am happy with it. I think it was $105 ish.

Problem with a OS rotor is they're more prone to damage due to their larger more exposed size...

As mentioned before, a steel braided line will make a noticeable difference in lever feel and brake performance.

All that being said, a 270mm over-sized rotor and braided lines are the ultimate in performance....

Here's what I have found with front brakes on Yamaha 's over the last 5 years:

 

#1 mod: 270mm rotor

#2 mod: replace Yamaha master cylinder with Honda master cylinder

#3 mod: braided brake line

#4 mod: Honda caliper

 

My 14 has a master and caliper off an 06 CRF250R, a Braking 270mm rotor, Galfer stainless brake line, and Galfer carbon pads.  One finger stoppies all day without feeling grabby.

Yeah I wasn't sure of the extra 10mm on the rotor was going to make a big difference. Interesting on the Honda parts. I still have an '07 CRF250R laying around.

I ran a honda master cylinder, honda brake pads, and an EBC 280mm rotor and felt the braking performance was good. I never tried a SS brake line, but I imagine it would have helped, but I was already happy with where it was at.

The OEM Yamaha brake line is braided stainless.

This is news to me. I've always been under the assumption they were nylon braided rubber with a hard plastic covering. Then again I've never had any reason to cut them apart to investigate further.

They are nylon or at least were in 2010 I shredded one to pieces on my 250.
