Hey guys

What's the best way to improve the brakes on the new gen Yamahas?
I read something about Honda parts, like you can just swap out the pads with Honda OEM pads but I'm not sure if that's also true for the current generation of bikes. And I guess a steel braided brake line would also help? I already have a oversize 270 rotor on it.

Thanks
Mike

CRF full system, and only use the Honda OEM lever.  Most all the aftermarket ones F with the geometry too much and they lose the solid feel.

I'm somewhat skeptical about this because my stock brakes on my 2009 CRF were pretty mediocre at best. My stock 2014 YZ had much better power with the 250 mm rotor than the CRF. When I put the 270 mm rotor on the Yamaha it was mildly improved. How would Honda parts make the YZ better?

Better lever geo, MC porting. Caliper is probably the same or similar. Just like to keep everything matched. Get sintered DP or OEM pads too.

I have been experimenting with YZF's '15 brake for over a year.

There was a lot of improvements with Braking Batfly 270mm and pads, but the brake was still soft.

The biggest improvement was achieved with Moto Stuff's Pro Lite steel braided brake line, which costs $150. I did try some other steel lines, but this one was much better. The reason why is because it is much thinner, only 2mm compared to 3mm stock line, requiring less oil for the same effect and it doesn't stretch. The stock lines are decent until 10-20 hours

There are other ways, imcluding Moto Stuff or Ride Eng. caliper. The RE caliper requires YZF's older master cylinder (11mm, up to 2007 YZ450F if I remember correctly), or Honda's cylinder.

If anyone is interested, I have a spare Moto Stuff Pro Lite steel line that would sell for $50. PM me
