About Us

We started our company in 2005 supplying quality motorcycle (and dirtbike and ATV) chains to the masses. Our warehouse has hundreds upon hundreds, really thousands of feet of chain. Color chain, drag race, motocross, streetbike, road race etc. We have not just the popular stuff but practically everything EK makes. We also stock all the master links for EK chains. Clip links, rivet links and screw links. Realizing some stores don't want to be bothered with small inexpensive items, we do sell a lot of master links. We will always be happy to assist you in getting the correct master link.

 EK Chains

We have choosen this small segment of the motorsports world to specialize in and believe we do it well.  We are so impressed with Enuma Chain Mfg. Co., Ltd. (EK) that's the only brand we carry! In 1974 Enuma introduced the world’s first sealed O-ring chain. In 1997 the company was certified to ISO 9001 quality management standards. EK has been known as the “legend of drag racing chains” and having the fastest chain in the world!

JT Sprockets

Such a great chain line wouldn't be complete without great sprockets to go with them. We carry the JT Sprockets line of steel sprockets, SCM415 chromoly steel alloy for the front and the only sprocket manufacturer using the ultra-durable high carbon C49 steel for rear sprockets. We stock all the popular ones and can order anything they have.

If you're looking for lighter weight racing rear color sprockets we can order for you Vortex racing CAT5 aluminum alloy.

About EK - In Race News

EK Chains have helped win numerous national and world championships in virtually every type of motorcycle competition, as attested by the No. 1 plates we proudly display on this page. EK equips the Kawasaki MotoGP team, the Amsoil/Chaparral/Factory Connection Honda motocross team, five-time AMA/Prostar Top Fuel Champion Larry “Spiderman” McBride, the Attack Kawasaki team of 2003 AMA Superstock Champion Josh Hayes, off-road legend Scott Summers, and the world’s fastest motorcycle, the 338-mph E-Z Hook Streamliner.
Kawasaki MotoGP Team
MotoGP bikes are built from prototype components that can handle more than 220 horsepower and speeds over 200 mph. So it might be a bit surprising that the Kawasaki Ninja ZX-RR bikes of Shinya Nakano and Alex Hofmann use the same off-the-shelf EK 520RXO chains that you can buy.

Amsoil/Chaparral/Factory Connection Honda Team
As Honda’s top motocross satellite team, the Factory Connection squad has the best of both worlds: factory-level equipment with the independence of a privateer. Led by Kevin Windham and Mike LaRocco, Factory Connection uses EK 520MRD chains on Windham’s CRF450 and LaRocco’s CR250, and 520MRDL chains on the team’s CR125s. The team’s 2004 AMA Supercross results speak for themselves: six 250 main event wins, 29 podiums, and not a single chain-related DNF since the team began using EK.
2004 Supercross season highlights: Six 250 main-event wins, 29 podiums, 2nd and 3rd overall in 250 championship, 125 winner at the U.S. Open of Motocross
2004 motocross season highlights: 7 podium finishes in 12 rounds, 3rd overall in 250 championship
EK chains: 520MRD, 520MRDL
2000-04 AMA/Prostar Top Fuel Champion: Larry McBride
In 2001, Larry “Spiderman” McBride became the first motorcycle drag racer to make a quarter-mile pass in under six seconds. In 2002, he became the first bike racer to run over 240mph in the quarter. In 2004, McBride did it again, lowering the E.T. record to an astounding 5.876 seconds at 244mph, and earning his fifth consecutive Top Fuel crown. Larry set every one of these records on his 1000hp Kawasaki-powered bike using the EK 630SHB, the world’s quickest and fastest chain.
2004 season highlights: Six consecutive Top Fuel wins, new national E.T. record
EK chain: 630SHB
2003 AMA Superstock Champion: Josh Hayes
After Josh Hayes claimed the AMA Superstock national championship for the Attack Performance team in 2003, he and the team took on a new challenge: developing the awesome Kawasaki ZX-10 into a competitive superbike platform. Operating with limited factory suport, Hayes and the Attack team compiled an impressive record of 12 top-ten finishes in 18 races, and eighth in overall points. Hayes ended the season with a repeat victory in the Toyota 200 at California's Willow Springs Raceway, a win that netted him a cool $50,000. The Attack team uses EK RXO Series chains.
2004 season highlights: Winner, Toyota 200, 12 top-ten finishes and three top-fives in AMA Superbike; five top-five finishes in AMA Superstock

World’s Fastest Motorcycle Rider: Sam Wheeler
On August 27, 2004, Sam Wheeler and his turbocharged Kawasaki ZX-11-powered E-Z Hook Streamliner recorded the fastest ever-terminal speed for a motorcycle, clocking 338.269 mph at the Bonneville Salt Flats. Sam uses the EK 530DRZ chain.

5-Time GNCC Champion: Scott Summers
A fan favorite wherever he goes, Scott Summers' unparalleled resume includes the facts that he was the first rider to win both the Cross Country or Hare Scrambles series on a four stroke, the first rider to win the Hare Scrambles title two years in a row; the first to finish a Cross Country season with a perfect score; has won both the Cross Country and Hare Scrambles titles twice in the same year and he's been the AMA Cross Country series' Rider of the Year six times, not to mention the three ISDE gold medals. Scott uses the EK 520MVXZ Quadra-X Ring chain on his Honda.
2004 season highlights: six top-five finishes and sixth overall in the GNCC series, in his first full season of racing since 1999
EK chain: 520MVXZ
Freestyle Motocross: Adam Jones
Starting out at the age of 10 on a KD80 his parents bought him, Adam Jones was on his way to becoming a known name in FMX. Winning eight IFMA competitions in his first year as a pro, Adam proved he has what it takes to ride with the best.
2004 season highlights: X Games freestyle bronze medal
EK chain: 520MVXZ
2003 AMA 250 GP Champion: Rich Oliver
When the AMA announced that 2003 would be the last year for the 250 Grand Prix Championship, four-time class champion Rich Oliver set out to stamp his name in the record books as the last-ever 250 titlist. He and mechanic Robert Ward wanted to save weight and maximize relibility, so they chose the EK 520MRDL, our smallest, lightest 520 chain. Though the non-sealed 520MRDL is normally used for 125 motocross racing, it had no problem withstanding the demands of Robert's 95hp, 14,000 rpm motor. The result? An unprecedented perfect season, with 11 wins in 11 races, and a fifth championship for Rich.
2003 season highlights: Undefeated in 11 straight AMA 250 GP races
EK chain: 520MRDL
2003 AMA Superbike Top Privateer: Shawn Higbee
Finishing sixth overall in the AMA Superbike Championship on his Millennium Kaufman Suzuki GSX-R1000 prepared by KWS Motorsports, Shawn Higbee showed that you don’t need a factory bike to ride with the big dogs. Shawn’s Gixxer uses EK 520RXO chain.
2003 season highlights:16 top-ten finishes in 18 races; AMA Top Privateer Award
EK chain: 520RXO
