EK/PBR 520MRD7 Chain Kit 13/50 - Standard Sprocket

Designed for off-road demands, this EK CHAIN kit combines a 520 chain with a standard profile 13/50 sprocket/crown pair. The gold finish gives a polished look to the drivetrain, while the construction aims to provide good resistance to traction and abrasion — qualities sought after in the muddy and rocky terrains of motocross.

• Type: Chain kit (13-tooth sprocket / 50-tooth crown - standard crown)
• Pitch: 520
• Number of links: 118
• Color: Gold / Gold
• Crown material: Steel
• Weight: 1.47 kg for 100 links
• Relative lifespan: 450 (for 100 links)

Suitable for competitive and training use in motocross, this kit is designed to withstand high demands (accelerations, jumps, changes in posture). It naturally fits modern enduros and motocross bikes — common models include KTM 250 XC (2026), HUSQVARNA TE 300 I (2022), KTM 300 EXC TPI SIX DAYS (2022) — provided that you check the exact compatibility with your machine.
