The 150R is an interesting mix of parts, a capable high-performance engine, a decent chassis, but the brakes are from a play bike and are terrible!

Massive amounts of caliper flex and easy for even a fast Junior rider to overheat them.

Big Red Base Kit Includes:

  • Our 250mm Blade Rotor
  • Lightweight Billet Aluminum Caliper bracket

This kit is designed to utilize a twin-piston caliper from the 2004-2020 CRF 250R or 450R.

This is the kit that we developed for GEICO/AMSOIL Team riders Cason Mumford and Chase Sexton.

Or if you don't have time to chase down those extra items, we do offer a complete ready to go bolt-on kit:

Big Red Full Kit Includes:

  • Brand new 2 piston floating caliper from the 2018 CRF 450R
  • Our massive 250mm Blade Rotors
  • Lightweight MOTO STUFF billet aluminum caliper relocation bracket
  • Lengthened steel braided front line in translucent red with the correct banjo fittings in anodized red for the big caliper
  • Set of our lightweight billet banjo bolts (Blue)
  • MOTO STUFF AP Racing Pads

The biggest advantage of moving to a larger front disc is that it significantly improves control (modulation). The increased diameter reduces the on/off light switch feel of smaller brakes and allows the rider to apply more brake force at the edge without locking up the wheel. 

Plus we use a more expensive 410 stainless alloy that provides 3-4 times longer life and consistent linear performance under high heat loads. The stock rotors and all other aftermarket rotors are made of common 420 stainless. And our single piece Blade design is the lightest oversized kit available and is 30-50% lighter than other kits available. 

Lastly, the popular floating design found on many current MX bikes was originally developed for road racing bikes where you have a 400-500 lb bike, and high traction (pavement) which makes it possible to generate extreme amounts of heat very quickly. So to keep the rotor from warping under those conditions, the floating rivets allow the swept area of the rotor to expand and contract in diameter without warping. Plus road bikes have fixed calipers, so some float in the rotor is needed to allow for any mild warping or impact damage from road debris, etc. We feel that floating rotor technology is misplaced on an MX bike as dirt, sand and water accumulate in the rivet surfaces causing rapid wear and play. This play is felt by the rider as inconsistent engagement in the brake system and you can often hear the metallic clicking under brake load when riding. All modern MX bikes have floating calipers designed to allow for .030" to .050" of rotor runout from impact damage without causing pulsing at the lever. There are a few top teams that use floating designs, but you'll also see the brake company at the races inspecting and replacing rivets and carriers when play develops. This requires some very expensive hydraulic press tools that are not available to the general public. GEICO HONDA has been using our Blade brakes for over 10 years.
