Kuiuk #35 Mini Bike Chain Kit 140-Link with Adjustable Rubber-Metal Tensioner, Master Links & Tool Set

Kuiuk 35-chain kit is a complete mini-bike and go-kart drive solution: a 140-link #35 roller chain with an adjustable rubber-metal tensioner, master links, chain breaker and wrench for Predator- and Coleman-powered small engines.

This kit provides the parts you need to repair or upgrade the drive system on a wide range of mini bikes and go-karts. Built from hardened alloy steel and finished for corrosion resistance, the 140-link #35 chain ships with hardware to size and secure the loop quickly. The included tensioner keeps chain slack under control while the master links and chain tool make field adjustments straightforward.

Will this chain fit my Coleman, Baja or Motovox mini bike?

The Kuiuk #35 chain and tensioner are designed for popular small-frame machines that use Predator-style engines. Compatibility covers Coleman CT100U and CC100X units, Baja/Doodle Bug DB30 family models, and Motovox MBX10/MBX11 frames, plus many mini bikes and go-karts running Predator engines from about 79cc up to 212cc.

• 140-link #35 roller chain length suits common sprocket spacing on these models.
• Works with Predator 79cc, 97–100cc, 98cc and 212cc engine-equipped machines.
• Includes master links and a breaker so you can trim chain length for custom fits.

How durable is the chain and tensioner under everyday use?

The chain is fabricated from high-strength alloy steel and finished to resist abrasion and rust, extending usable life under normal riding conditions. The rubber-metal tensioner uses an adjustable mounting design to maintain correct chain tension while damping vibration that would otherwise accelerate wear.

• Alloy-steel rollers and links for improved load tolerance.
• Surface treatment reduces corrosion and friction-related damage.
• Rubber-metal tensioner cushions sprocket engagement and reduces noise.

What tools and parts are included to install and adjust the drive chain?

The kit ships ready for installation with everything needed to size, secure and tension the chain without purchasing additional items. A chain breaker and wrench let you remove excess links and fit the master link; the package also includes ten master links so you have spares for future repairs.

• 1 x 140-link #35 chain, pre-measured for common mini-bike setups.
• 1 x adjustable mini-bike chain tensioner and mounting hardware.
• 10 x master links, 1 x chain breaker, 1 x wrench for cutting and assembly.

How do I maintain the chain to maximize performance?

Routine cleaning and lubrication will prolong chain life and maintain smooth power transfer. Inspect the tension, sprocket wear and master links regularly and replace any components showing significant wear or corrosion to prevent failures during use.

• Lubricate rollers and pins after cleaning with a light chain lubricant.
• Check tension regularly and adjust the included tensioner as needed.
• Replace master links if pins show elongation or visible damage.

Who this kit suits: the Kuiuk 35-chain assembly is aimed at hobbyists, mechanics and owners of compact recreational bikes or karts who need a robust replacement chain and the hardware to fit it. If you maintain Coleman CT100U/CC100X models, Baja/Doodle Bug DB30 family machines, Motovox MBX10/MBX11 units or any small-frame vehicle powered by Predator engines in the 79–212cc range, this package gives you the chain, tensioner and tools required for a tidy, durable installation.
