EK/PBR Chain kit 520 MRD7 - 14/50-118 - Alu Standard Rear Sprocket for KTM SX 250, XCF 350 and HUSQVARNA FC 350, TC 250

EK CHAIN offers this chain and sprocket kit for KTM MX 250, SX 250, SXF 350, SXF 450, XCF 350 and HUSQVARNA FC 350, FX 350, TC 250 1992-2027. The front sprocket, on the gearbox output, drives the chain, which turns the rear sprocket bolted to the rear wheel.

Why replace the whole kit?

The benefits:

• A worn chain damages the teeth and worn teeth damage the chain: replacing all three parts together avoids ruining a new part within a few rides.
• Pitch, tooth counts and chain length are already matched: one order for the whole final drive.
• You can adapt the gearing: more teeth on the rear sprocket (or fewer on the front) gives more acceleration but less top speed; fewer teeth on the rear does the opposite.

When should you replace this part?

Hooked or pointed teeth, a chain that lifts off the back of the rear sprocket when pulled, tight spots or slack that needs adjusting every ride: the kit is worn out.
