Custom developed by BBR Motorsports for the ultimate upgrade for mini four-strokes. Sized perfectly for fast/aggressive adult mini riders. This is the most important upgrade you can make for an adult sized rider. The stock suspension is too soft for most adults.

• 30% stiffer than stock
• Preset and stress relieved for long life
• Custom wound from aircraft quality spring steel

Important Note: These springs will fit the KLX140G (18”/21” Wheels). They are not for use in the standard KLX140 or KLX140L
