The Moose Offroad 420 RXP Pro-MX Chain is built for riders who demand dependable power transfer on mini motocross racing machines. Its non-sealed (non O-ring) design helps reduce rotating weight and drag for a responsive feel, while the chain comes high-application greased to support hard riding and frequent acceleration.
With nickel-plated high-tensile inner link plates and rust-resistant gold-plated side plates, it’s designed to hold up in dirty, wet, and high-wear off-road conditions—making it a smart choice when you want consistent drive and easy maintenance for smaller-displacement bikes.
