Rear Sprocket MOOSE OFFROAD HARD - PARTS (manufacturer ref: 853-40AL) — aluminium crown designed for quads and ATVs. Computer-designed and CNC machined (not stamped), this 7075 T-651 aluminium crown offers a weight/strength compromise suitable for off-road conditions. Intended for the rear position and a pitch of 520, it features 40 teeth for mounting on corresponding chains.
The choice of 7075 T-651 aluminium helps reduce unsprung mass without sacrificing resistance to typical off-road stresses. CNC machining ensures precise tooth geometry and a more secure fit than a stamped part. The groove-free design promotes a more uniform contact between the aluminium and the chain, which can contribute to more even wear of the crown.
Suitable as a replacement part for many quads, including the YAMAHA YFS 200 Blaster (2001–2006) listed among common applications. Always check the pitch and number of teeth before installation to ensure optimal compatibility.
