PBR Standard Steel Sprocket 7005 - 420 (Manufacturer reference: 7005 14 18NC)
Designed by PBR with experience from competition, this standard version 7005 sprocket is aimed at motocross riders looking for a reliable part for both training and racing. Machined from quality steel, it meets the technical specifications expected for a 420 transmission and ensures a precise fit with the chain.
The 18NCD5 alloy used by PBR offers good resistance to corrosion and abrasion according to manufacturer specifications and aims to minimize friction between the sprocket and chain. The result: smoother rotation and a more reliable transmission for your off-road sessions.
Practical compatibility: this sprocket is commonly fitted on 65 cc motocross bikes such as KTM 65 SX (2025), HUSQVARNA TC 65 (2025), and GAS GAS MC 65 (2025). However, please check the number of teeth and chain pitch of your machine before installation.
