Calipers & Mounts

The MOTO STUFF WORKS EDITION Billet 1-Piece Caliper  

20% lighter than the stock cast aluminum NISSIN calipers found on HONDA, KAWASAKI, SUZUKI, and YAMAHA MX bikes. Our new billet construction design is an exact replica of the WORKS NISSIN part found on top factory team bikes like Ken Roczens HONDA CRF 450R and Eli Tomacs KX450F, All GEICO bikes, etc. The only difference is that our design is compatible with stock caliper brackets and fork lug spacing!

The worlds only aftermarket differential bore caliper! (2 different piston sizes) for modern MX bikes. The differential bore design uses a 27mm piston on the leading edge and a larger 30mm piston on the trailing edge. This design eliminates the uneven pinching effect (uneven force distribution) that naturally occurs whenever you apply a clamping force to a rotating component. The balanced force dispersion provides lower operating temps, reduced brake fade, reduced wear and most importantly more controllable and consistent modulation and power. As the surface of the rotor heats up, the clamping force of the pistons has to be increased to avoid brake fade. 

Kit Includes:

• 1- Piece 7025 Billet Alloy Housing Body
• 2- Lightweight 7076 Alloy Pistons (27mm leading edge and 30mm trailing edge)
• 1- Trick Lightweight Stainless Steel Lower Slider Pin with safety wire feature
• 1-Hardened Slide Post
• 1- Stainless Bleeder Screw
• 1- Billet Aluminum Banjo Bolt drilled for safety wire (Anodized Blue or Red)
• 1- Stainless Steel Pad isolator clip and Anti-rattle Clips
• 1- Set of AP Racing Pads, best available!

OPTIONAL UPGRADE: If you are severely abusive and fast enough to fade your brakes or you just love really trick stuff, we can build your caliper with our ultra trick Titanium Nitride coated Titanium castellated pistons. The thermal conductivity of Titanium is 10 times lower than Aluminum! The castellated crown (semi-circle cutouts milled into the piston crown) provides airflow to the backside of the piston further improving fade resistance. You can add select the Ti Piston option above.

Key Features and Benefits:

1. The worlds only aftermarket differential bore caliper (2 different piston sizes) for modern MX bikes. The differential bore design uses a 27mm piston on the leading edge and a larger 30mm piston on the trailing edge. This design eliminates the uneven pinching effect (uneven force distribution) that naturally occurs whenever you apply a clamping force to a rotating component. The balanced force dispersion provides lower operating temps, reduced brake fade, reduced wear and most importantly more controllable and consistent modulation and power. As the surface of the rotor heats up, the clamping force of the pistons has to be increased to avoid brake fade. 
2. Billet one-piece body with massive bridge structures reduces flex by 28%, which improves consistency and response at the lever. Providing more controllable stopping power with less effort and helps reduce arm pump and rider fatigue.
3. We've also incorporated a new piston seal design that provides a pull back feature which pulls the pistons .020" - .030" away from the pads slightly after each brake application eliminating rotor drag. 

Fits all current MX bikes except KTM/HUSKY

PLEASE NOTE the two following important details:

1. 2019 and 2020 HONDA CRF models will require a 2015-2018 caliper bracket. Either OEM or one of our oversized brake kits for 2015-2018. This is because the 2019 and 2020 models have a different bolt hole pattern on the caliper pin spacing.
2. 2007-2020 Yamaha models will require that you upgrade the Master Cylinder. Available here- 11mm Master cylinder Upgrade

The MOTO STUFF Billet 1-Piece Caliper is available for most modern (2004-2020) HONDA, KAWASAKI, SUZUKI and YAMAHA MX bikes (including 2 strokes) and it is a great compliment to the MOTO STUFF Blade Braking System! The MOTO STUFF "WORKS EDITION" caliper is ready to bolt on and equipped with premium components including stainless steel sliding pin, Billet Banjo bolt, billet Bleeder cap and AP Racing pads. A true works level caliper at an affordable price!

DOES not fit KTM or HUSKY!

MOTO STUFF Caliper Brackets are precision machined from T6061 aluminum billet. After machining they are media tumbled for a smooth finish and then hard anodized for superior strength and performance. Our brackets are up to 50% lighter and 70% stronger than other brackets on the market. This is achieved through FEA model analysis and detailed machining processes.

Please Note! A bracket is included with all MOTO STUFF Brake kits, so these are for use as replacements if you somehow damage one or have a compatible 280mm rotor from another manufacturer.

If you have any questions about compatibility or fitment, please give us a call or send us an e-mail to info@MOTOSTUFF.COM
