Moose Offroad 1210-1509 Dual Rear Sprocket for 1990-1995 Suzuki DR350 DR250 — 48T Silver

Moose Offroad 1210-1509 Dual Rear Sprocket — Lightweight Strength and Enhanced Durability for Suzuki, Beta, and Gas Gas

Get the best of both worlds with the Moose Offroad 1210-1509 Dual Rear Sprocket. Engineered for demanding off-road, adventure touring, and dual-sport applications, this premium 48-tooth rear sprocket delivers a smart hybrid build. It provides the lightweight, power-saving performance of aluminum alongside the uncompromising wear resistance of high-grade steel, ensuring a reliable drivetrain refresh for your Suzuki DR, Beta RR, or classic Gas Gas machine.

The advanced dual-material construction features a lightweight inner carrier ring machined from aircraft-grade 7075-T6 aluminum, drastically trimming down unsprung rotational weight compared to solid steel alternatives. This inner ring is bound securely to an ultra-hard, heavy-duty steel outer ring containing the teeth, guaranteeing a long-lasting service life that outlasts conventional aluminum sprockets by up to three times. Optimized for rough terrain, the sprocket incorporates precision self-cleaning mud grooves situated between each tooth. These specialized channels actively shed dirt, grit, and mud buildup, protecting your 520 drive chain from premature stretch and maintaining smooth power transfer on muddy trails.

Key Performance Benefits

• Hybrid Dual-Material Architecture: Combines a 7075-T6 aluminum inner core with a heavy-duty steel outer ring to achieve maximum strength with minimal weight.
• Extended Wear Resistance: Hardened steel outer teeth easily withstand the abrasive friction of dirt and sand, providing up to three times the longevity of standard aluminum.
• Self-Cleaning Mud Grooves: Uniquely machined relief channels prevent mud packed by the chain from accumulating, lowering chain tension stress and drag.
• Reduced Rotational Mass: Shaving off unnecessary weight from your rear hub improves rear suspension response and maximizes throttle snap.
• Precision Factory Alignment: Cut to exact engineering tolerances for standard 520 chain sizes, guaranteeing a quiet, true-running final drive assembly.

Moto House MX Pro Tip:

Whenever you change out your rear sprocket, we strongly advise installing a brand-new 520 drive chain and matching countershaft front sprocket at the same time. Running a new sprocket with an old, stretched chain or worn front cog causes asymmetrical wear patterns that will dramatically shorten the operational life of your premium new dual sprocket.

FAQ Questions

Q) What are the main advantages of a dual-material sprocket over a solid steel one?
A) A dual-material sprocket gives you the exact same long wear life on the teeth as a solid steel sprocket, but it cuts down significantly on rotational weight due to its lightweight 7075-T6 aluminum inner carrier ring.

Q) Will this sprocket fit a heavy-duty O-ring or X-ring style 520 chain?
A) Yes. This sprocket is precisely machined to accept all standard 520 drive chains, including traditional roller, O-ring, and sealed X-ring off-road chains.
