ProComp Swingarm Kit with Elka Shock

The BBR Motorsports 330-HCF-1230 is a ProComp swingarm kit engineered to enhance the rear suspension of CRF125F/FB and CRF/XR100 motorcycles. This kit is designed to be approximately 1 1/4" longer than stock, resulting in an increased ride height of 2" to 2 1/2" depending on the specific model. The swingarm itself is machined from solid billet 6061 aluminum, featuring a pocketed design that maintains stiffness while minimizing weight. It comes equipped with a welded chain guide mount and includes the BBR Works Edition Chain Guide. The swingarm is compatible with the OEM CRF125F/FB or CRF/XR100 rear hub. This kit integrates an Elka Stage 4 shock, complete with an 1100 lb spring, and offers the option to upgrade to a 1200 lb spring for heavier riders or specific performance needs. Note that this kit requires a longer chain and potentially modifications to the front end to match the increased rear ride height, such as using longer CRF100F or XR100R (1985 and newer) fork legs. Important considerations for installation include that this kit replaces the stock linkage and shock system; your original or other aftermarket shocks will not be compatible. The product listing also notes that CRF/XR80 owners can use this swingarm, but it will be significantly longer, leading to a much higher seat height, and will require front-end adjustments to compensate. For CRF125F/FB owners, BBR CRF125F triple clamps are recommended, while CRF/XR80/100 owners can use BBR CRF/XR80/100 triple clamps (sold separately).
