YOXUFA T8F Chain Kit 116-Link + 54T 54mm Bore Rear Sprocket for 43–49cc Mini Moto — Alloy Steel, Includes Chain Breaker

YOXUFA T8F Chain Kit is a complete drivetrain replacement that includes a 116-link T8F chain, 54-tooth rear sprocket (54 mm bore), master links and a chain breaker for 43–49cc mini motos and pocket bikes.

This kit replaces worn or damaged rear drive components on small-displacement two-stroke bikes and ATVs. Built from alloy steel components, the set is engineered for improved wear resistance and a secure fit that reduces chain slack and the risk of derailment. It arrives with the hardware and a chain breaker so you can install or repair your drivetrain without searching for extra tools.

How does this kit fit my 43–49cc bike or pocket bike?

The kit is tailored to a long list of small-engine models commonly used for mini dirt bikes, pocket bikes and some ATVs. The sprocket’s center bore and bolt pattern match many 43–49cc platforms, and the 116-link T8F chain length suits typical rear-center distances found on these frames.

• Fits Syx, Holeshot, Coolster, Mototec, SSR SX50 and similar models
• Sprocket center hole: 54 mm (2.13"), bolt circle: 65 mm (2.56")
• Includes 116-link T8F chain and 10 master links for secure joining
• Comes with a chain breaker to size or repair the chain on-site

What materials and durability can I expect from the chain and sprocket?

Both the chain and sprocket use hardened alloy steel intended to resist wear from grit and repeated loads. The parts are finished and toleranced to maintain chain tracking and minimize premature stretching when properly installed and maintained.

• Alloy steel construction for improved abrasion resistance
• Precision-cut teeth to reduce irregular wear and noise
• Durable finish to slow corrosion in outdoor conditions
• Designed to pair precisely with T8F chain geometry to avoid derailment

What tools and extras are included to help with installation?

The kit includes practical accessories so you can fit the chain and sprocket without buying specialty tools. A chain breaker lets you adjust length and replace pins, while spare master links provide fast, secure reconnects during installation or roadside repairs.

• Chain breaker for cutting and pin replacement
• Ten master/connect links for immediate joining
• Hardware dimensions provided to confirm bolt pattern and bore fit
• Clear compatibility list to cross-check model fit before installation

How will this kit affect my bike’s performance and maintenance?

Replacing a worn chain and sprocket restores drivetrain efficiency and improves throttle response by minimizing slop and uneven engagement. Regularly checking tension and keeping the chain lubricated will maximize service life and reduce noise and vibration.

• Restores consistent power transfer and smoother acceleration
• Reduces risk of chain skip or derailment with matched components
• Easier maintenance thanks to included master links and tool
• Recommended to recheck tension after initial run-in period

Who is this for: This YOXUFA T8F chain kit is aimed at owners, mechanics and hobbyists who maintain 43–49cc two-stroke mini motos, pocket bikes, small ATVs and pit bikes. It's a convenient, ready-to-install option for riders replacing worn drive parts or upgrading to a matched chain-and-sprocket set that includes installation aids.
