RFX Pro Series Elite Aluminum Sprocket - 415: a part designed for off-road, intended for small displacement motocross bikes. CNC machined from 7075 aluminum, this sprocket combines lightness and strength to withstand the demands of the track while facilitating acceleration and re-acceleration. The mud evacuation grooves limit clogging between the teeth and chain, extending its use in muddy conditions.
- Manufacturer reference: FXRS 57-41 99BU
- Material: CNC machined 7075 aluminum
- Number of teeth: 41
- Chain pitch: 415 (compatible with 415 chain)
- Color: Anodized blue
- Type: Standard
- Laser-engraved RFX logo and specific color code by brand for an aesthetic and identifiable installation.
- Profile designed by CAD for weight reduction; rigid design and tight tolerances for better torsional strength.
Suitable for 50cc motocross bikes and short track outings, it is particularly compatible with KTM 50 SX (2025), HUSQVARNA TC 50 (2025), and GAS GAS MC 50 (2025) models. Replaces an original 415 sprocket while maintaining the alignment of the transmission: check the number of teeth and standard before installation.
