All motorcycle chain regardless of brand is a consumable product; which means that it will not last forever and will eventually need to be replaced. RK Chain suggests that chains need to be replaced every 20,000 miles and every 3,000 miles for non-sealed chains. You should also change both the front and rear sprocket whenever you replace the chain.
RK Chain recommends cleaning a sealed chain with only a mineral based O ring safe chain cleaner. Do not use kerosene, brake cleaner, motor oil or any caustic chemicals because that can damage the seals. RK recommends that you douse a rag with the mineral based O ring cleaner and wipe the dirt off the chain. Do not use a wire brush or hard bristle brush to clean a sealed chain. The wire or hard bristles can damage the seals reducing the life of the chain.
RK Chain recommends that after cleaning the chain and before lubrication, go for a short ride around the block to remove most of the chain cleaner and or water from the chain. RK recommends that you then follow up with a quality chain lubricant designed for sealed chains while the the chain is still warm.
DO NOT USE KEROSENE OR WD40 ON A SEALED CHAIN!

Cleaning a non sealed chain is the same as a sealed chain. RK Chain recommends cleaning a non-sealed chain with only a mineral based O ring safe chain cleaner. Do not use kerosene, brake cleaner, motor oil or any caustic chemicals. RK recommends that you douse a rag with the mineral based O ring cleaner and wipe the dirt off the chain.
After cleaning the chain and before lubrication, go for a short ride around the block to remove most of the chain cleaner from the chain. RK recommends that you then follow up with a quality chain lubricant and apply to the chain while the chain is till warm.
RK Chain has an exclusive warranty on all sealed chains NOT used for racing purposes. For street sealed chains not used in racing, there will be a pro-rated 20,000 mile warranty. For off road sealed chain not used for racing there is a 1 year pro-rated warranty. There are some stipulations to the warranty. For complete information see the warranty card that was included with your sealed chain.
Racing will VOID warranty Chain must be appropriate for the motorcycle. Chain must have been installed correctly and with drive system properly aligned. Chain must have been maintained. NO rust, corrosion, or other signs of neglect. Warranty does NOT cover contingent damages.Company recommend that every RK Chain be installed using a chain tool. Some tools, like the RK Chain tool UCT2100(50), combine all the parts needed to break the chain, cut it to length and clip or rivet the connecting link.
Using tools that weren’t designed for chain installation and/or removal may damage your chain and/or cause a dangerous situation and may void any warranty.
The flare can be as little as 0.152mm to 0.5mm but should never be over 0.7mm. The rivet pin should be flared just enough to keep the sideplate on, but not flared too much to bind the link.
RK’s new UCT2100(50) tool features a newly redesigned Flare Pin Tool that will prevent over-flaring of the rivet pin. *This only applies to the NEW UCT2100(50) tool not previous generations of UCT2100.
The answer is yes and no. It is true that initially non-sealed chains do produce less friction when compared to sealed chains.
However as time/rpm increase, sealed-ring chains significantly outperform non-sealed chains.
During normal use chains heat up and expand; this expansion can create friction resulting in horsepower loss. Due to the increased internal lubrication of sealed-ring chains, friction is reduced, allowing the chain to more freely transfer horsepower to the ground.
A sealed chain will last longer. That saves you money in the long-run.
Absorbs torque and improves acceleration
RK’s sealed ring chains offer less torsional friction and increased high-stress, high-speed performance. From the beginning of a race to the end; RK’s sealed ring chains deliver more consistent horsepower to the ground than non-sealed chains.
The nitrile butadiene seals ensure that lubrication stays inside the chain while keeping dust and dirt out. Most RK Chain seals have lubrication pools that protect against high speed abrasion, heat buildup, torsional flex and loss of lubricant under extreme conditions, resulting in longer life for the chain and sprockets.
Rims that have been anodized require special care. DO NOT USE SIMPLE GREEN ON ANODIZED RIMS! Simple green can strip the anodizing color away from the rim surface.
Wash rims with a PH balanced soap (shampoo) using a gentle rag and rise with water thoroughly. It is NOT recommended to use a pressure washer to clean rims.
Cracks around the nipple holes indicate over-tightening of the spoke and nipples. Nipples should never be over tightened. Whenever you lace or true rims Excel always recommends using a spoke torque wrench. You can maximize your wheel strength by torquing the spokes/nipples to the appropriate specifications suggested by the manufacturer. Excel produces an adjustable torque wrench designed to tighten your nipples to the appropriate specs.
Excel stopped producing the Excel Pro Series Gen1 hub almost 12 years ago. The redesigned Gen2 Hubs featured stronger technology for the increasing Horsepower of current motorcycles. While replacement product was produced for the Gen 1 hubs for several years after the discontinuation, Company have since ceased making any Gen1 product. If you still have an Gen1 hubs and need new spacers contact us. Company will check inventory to see if Company still have the part number. If Company do not have the part number Company can supply you with the spacer drawings so that you can have a machine shop create the spacers for you.
If you need replacement carriers and company no longer have stock of the part number, then unfortunately you will have to upgrade your wheelset hub and components to the newest generation G2 hubs/carriers. Please note that Gen1 carriers/spacers and Gen2 carriers/spacers re NOT interchangeable. Company do offer discounts for these upgrades as long as you send us your current Gen1 hubs/carriers.
Yes you can. Each letter and number of the Excel part number system identifies the various aspects of the rim.
