BBR worked with Elka Suspension to come up with a high quality, rebuildable, adjustable pitbike shock. The result is their brand new aluminum body Stage 2 playbike shock. A perfect match to our Stock Comp (or older generation Super Stock) swingarms, these Elka shocks feature adjustable rebound damping, adjustable preload, and a giant 16mm shock shaft. We had Elka valve these shocks for aggressive adult riders (and fast kids) and they're sprung for 165-200 lbs. riders.Stock KLX110 (non-L) shock is 255 mmStock KLX110L is 272 mmElka Stage 2 shock is 272 mm Adjustable spring preload Adjustable rebound damping Light weight hard anodized aluminum body Huge 16mm shock shaft Low friction internals Triple sealing seal head design 272 mm in length (approx. 10.7 inches) Made in Canada Note: Factory service and parts are available directly available from Elka Suspension (www.elkasuspension.com) in Canada or from Impact Solutions (www.impactsolutionsatv.com) in the US.
