Stop the stretch and eliminate sluggish final drive lag for good. The stock 428 on the 125cc models is severely overworked on a heavy 180kg machine, making a premium final drive overhaul the safest way to gain crisper performance and long-distance durability during your next maintenance project.  The 250cc models will just get a better chain that lasts longer than original Korea ones!

• Optimised Gearing // Specifically ratioed sprocket configurations wake up your torque curve to deliver better zip without over-stressing internal valves.  (A little acceleration boost while still hitting 80+ mph – Good for hills or quick sprints!)
• Premium Chains // Supplied exclusively with genuine Japanese or European link lines from premier brands like RK, EK, DID, DC, or JT. .
• Bonus Pack Additions // Arrives completely loaded with free stainless steel rear sprocket bolts and a new front sprocket lock washer.
• In Stock // Ready for your final drive system maintenance work. Bring heavy-duty 600cc-grade strength directly to your rear wheel assemblies.

⚠️ CHAIN QUALITY ASSURANCE: Cheaper kits on other websites use Chinese MTX/CHOHO chains that stretch quickly and can snap. We sell mechanical insurance—proven brands you can trust at 10,000 RPM. For 250cc owners, it is not fun being 100 miles away from home due to a snapped chain! #GoFaster!
