This kit includes six class 10.9 zinc plated steel sprocket bolts with factory style class 10.9 Fuji metal-locking nuts and washers. Each sprocket bolt has medium strength thread lock patches pre-applied, which liquefies and anaerobically seals when the bolt is tightened for a double-lock. This kit also includes an 8mm socket tool insert for socket wrenches.

Fits all Japanese and most European dirt bikes.

Our hardware meets or exceeds OEM specs. Proudly designed and assembled in the USA with components from the USA & Taiwan.

Important installation information:

Hub-Savers are the strongest, most complete sprocket fasteners available and have been developed and tested at the professional level in both motocross and off-road applications.

Sprocket bolts are a critical fastener and must be installed properly to ensure your safety and to avoid damaging your machine. To ensure long and reliable use of these quality fasteners:

• First clean and inspect your hub. If the hub is damaged or if the mounting holes are oval, the hub must
• Use the included Allen insert in an 8mm socket wrench to install the sprocket bolts.
• Refer to your owner’s manual for the proper torque (typically 25 ft-lbs), take the torque reading on the nut side. Never over-tighten sprocket bolts!

If your sprocket bolts become loose, they must be replaced! Sprocket bolts become loose only under extreme stress, an indication that either they were installed improperly or there is a problem with the driveline. Check the driveline for bent chain guides, bad wheel alignment, damaged mounting holes on the hub, etc. Properly tightened sprocket bolts on properly functioning drive lines will remain tight indefinitely.

CYCRA Disc Guard options and applications Please select the appropriate kit from the options below:

2013 & 2021 HONDA CRF 250R & 450R The CYCRA oversize disc guard requires a special standoff adapter to allow the use of the Cycra Disc Guard for 240-280mm diameter brake rotors. This kit includes the Cycra guard in Works Clear (same color as the stock disc guard) or Factory Black. Also included is the required standoff spacer for the lower rear mount and all mounting fasteners. Easily installed in about 5 minutes with common hand tools. Protect your brake rotor and caliper form debris for maximum performance and longevity. To order, select your color choice from the options above! 2 steel fork guard/disc guard bolts are included. Red, blue or silver billet fasteners can be ordered separately in our accessories category.

2009-2012 HONDA CRF 250R & 450R On these models HONDA introduced a disc guard that is integrated with the axle spacer. This design prevents the use of the popular CYCRA disc guard when running oversized brakes. We worked with the GEICO HONDA Race team to develop this easy to install adapter kit (this is a complete kit including CYCRA disc guard) that allows you to run the CYCRA oversize disc guard compatible with 240mm to 280mm rotors and protect your brakes from the elements. Easily installed in about 5 minutes, our kit provides a strong yet lightweight billet aluminum factory style mount. You will have to press or cut the axle spacer out of your original disc guard or you can order one of our popular billet vented axle spacers or the ZETA Red axle spacer set available in the brake and wheel sections of our website too. To order, select your color choice from the options above! 2 steel fork guard/disc guard bolts are included. Red, blue or silver billet fasteners can be ordered separately in our accessories category. 

2002- 2008 HONDA CRF 250R & 450R The CYCRA Oversized Disc guard is a direct bolt-on replacement for the stock disc guard and can be used with oversized rotors from 240mm up to 280mm in diameter. Available in Factory Black or Factory Works Clear (same color as the stock disc guard and fork guards).

CLOSEOUT!

Why upgrade your brakes? You can easily lock them up and slide/skid now, right? That's the problem. Modern motocross bikes have very powerful brakes, however, they don't offer much in the way of modulation or linear application. That is the ability to achieve maximum braking force without wheel lock-up.

As soon as the wheel locks up, you lose control or much worse! Power without control is why 4 strokes hook up and outperform 2 strokes. Your ability to modulate (control) the braking force is what makes for a great brake that you can put to maximum use. MOTO STUFF Blade^tm brakes are the highest quality and absolute best performing brakes you can buy.

Team HONDA and the GEICO Factory Connection team have been winning titles with MOTO STUFF Blade^tm Brakes for several years. They can run any brakes they want and they choose the MOTO STUFF Blade System as it provides ultimate performance and significantly improved durability, heat rejection and lasts 2-3 times longer than the competition. Wide modulation range, linear and consistent performance rapidly builds your trust in your brakes at the limit. Below are the main benefits you’ll enjoy with a MOTO STUFF BLADE SYSTEM that will improve your competitive edge!

• 36% increase in swept area and 18% increase in moment arm for dramatic improvement in braking power, control and modulation. (AKA The ability to develop maximum stopping power without locking up the brakes)
• Trick lightweight design of the Moto Stuff Blade System weighs only 544 grams (19.2 oz) and looks like nothing else on the market. Nearly a full pound lighter than inferior floating designs. The Blade system is 40% lighter than any other 280mm system. That is huge! Title winning teams spend thousands of dollars on Titanium axles and fasteners to shed 8-10 oz's off the front suspension. This is also unsprung and rotating weight, every pound of reduced unsprung weight is the equivalent of 3 pounds savings of sprung weight off the chassis. Reducing rotational mass also has a noticeable positive effect on turn-in and overall handling.
• 280mm rotor laser cut and machined in heat-treated 400 series stainless steel for warp-free performance and superior heat dissipation. Moto Stuff Blades typically last 2-3 times longer than the competition!
• Hi-strength 6061 billet aluminum bracket is hard anodized for a tough long-lasting finish. Rotor material is compatible with all top-quality aftermarket pads, we recommend stock pads or our AP Racing Pads for best performance.
• Easily installed in under 30 minutes with common hand tools
• 1-year warranty against defects in material or workmanship

Beware: You can not use the 2004-2014 bracket on the 2015 & 2018 model as it will position the caliper 5mm too far out and could lead to a situation where you have no brakes!

On 2009-2014 models you'll need to press the axle/wheel spacer out of the disc guard. Our rotor is too large for the stock disc guard.  CYCRA and ACERBIS guards do fit with our 280 rotors. 

NOTE: 2019/2020 is all new (2015-2018 calipers and brackets do not fit the 2019/2020)

Give us a call or email anytime you are unsure of a fitment and we'll be glad to help. 

KIT INCLUDES

• MOTO STUFF 280mm Rotor
• MOTO STUFF "Superlight" Billet Mounting bracket

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.
