KTM Factory Racing front wheel 1.6x21" A46009901544C1A
The KTM Factory Racing front wheel 1.6x21" A46009901544C1A is a lightweight, high-strength front wheel assembly developed for modern KTM Group off-road motorcycles. A CNC-machined, anodised aluminium hub, reinforced steel spokes and anodised aluminium spoke nipples combine to reduce rotating mass while improving stability and steering precision in demanding enduro, cross-country and motocross conditions.
Key features
- Anodised hub machined from a single piece of aluminium for maximum strength and durability.
- Optimised 1.6x21" front wheel size for precise steering feedback and accurate line choice in ruts and technical terrain.
- Significant weight reduction compared with standard wheels for more agile handling and faster direction changes.
- Reinforced spokes for higher impact resistance under hard landings, rocks and braking bumps.
- Anodised aluminium spoke nipples for reduced corrosion, consistent spoke tension and premium Factory Racing look.
- Black anodised finish for a durable, scratch-resistant surface that matches current KTM off-road model styling.
- Designed as a complete Factory Racing front wheel assembly for competition-level off-road use.
