Improve front-suspension balance, handling, and predictability with the Race Tech Fork Spring 0.46 kg/mm, manufacturer part number FRSP 444546 and vendor part number 200-444546. Designed for riders who need accurately matched spring rates, this high-performance fork spring helps address the under-sprung condition common on sport and motocross motorcycles. Selecting the proper rate can improve control, chassis stability, and rider confidence across a wide range of riding conditions.
Race Tech manufactures this spring from chrome silicon wire for a high stiffness-to-mass ratio and consistent performance. The spring is shot-peened and heat-treated to support long-term durability, while its accurate rate is designed to resist sacking out over time. This makes it a dependable replacement or suspension-tuning component for riders seeking more predictable fork response without unnecessary weight.
This Race Tech 0.46 kg/mm fork spring fits select 2007 KTM 250 SX, 2007 KTM 250 SX-F, and 2007 KTM 450 SX-F models, along with 2006 through 2012 Yamaha YZ125 motorcycles.
