Medium covers 140 to 180 pounds with 4.0\/4.0 springs. Heavy covers 180 to 220 pounds with 4.4\/4.0 springs. Rates are listed left side \/ right side.\u003c\/p\u003e\u003ch3\u003eDoes it pair with the Sirris R38 shock?\u003c\/h3\u003e\u003cp\u003eYes. The R38 is tuned to pair with the F43 CMX fork. Its linkage raises the rear 25mm, and the drop clamp raises the front by the same 25mm to keep the bike level.\u003c\/p\u003e\u003ch3\u003eWhat does the drop clamp do?\u003c\/h3\u003e\u003cp\u003eIt adds 25mm of extended length. That extra length is what makes a 21 inch front wheel conversion possible.\u003c\/p\u003e\u003ch3\u003eCan I keep my stock stem?\u003c\/h3\u003e\u003cp\u003eOnly if it is a 4-bolt direct mount stem. The Sirris steer tube cannot be clamped, so a stem that clamps around the steerer will not work.\u003c\/p\u003e\u003ch3\u003eWhat does CMX tune mean?\u003c\/h3\u003e\u003cp\u003eCMX is Sirris's Compact Motocross Tune. It is the damping setup built for small, light E-motos ridden hard, not a full-size motocross valving shrunk down.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eShips from USA!\u003c\/strong\u003e\u003c\/p\u003e","brand":"Charged Powersports","offers":[{"title":"Medium (140-180 lb) \/ CMX - Standard Clamp \/ Black","offer_id":60933164499230,"sku":"430-99-014-MED-02-F43-775X220-ERIDEPRO-SR-BLACK","price":2250.0,"currency_code":"USD","in_stock":true},{"title":"Medium (140-180 lb) \/ CMX - Standard Clamp \/ Blue","offer_id":60933164531998,"sku":"430-99-014-MED-04-F43-775X220-ERIDEPRO-SR-BLUE","price":2250.0,"currency_code":"USD","in_stock":true},{"title":"Medium (140-180 lb) \/ CMX - Drop Clamp \/ Black","offer_id":60933164564766,"sku":"430-99-014-MED-02-DROP-F43-775X220-ERIDEPRO-SR-BLACK","price":2350.0,"currency_code":"USD","in_stock":true},{"title":"Heavy (180-220 lb) \/ CMX - Standard Clamp \/ Black","offer_id":60933164597534,"sku":"430-99-014-HEAVY-02-F43-775X220-ERIDEPRO-SR-BLACK","price":2250.0,"currency_code":"USD","in_stock":true},{"title":"Heavy (180-220 lb) \/ CMX - Standard Clamp \/ Blue","offer_id":60933164630302,"sku":"430-99-014-HEAVY-04-F43-775X220-ERIDEPRO-SR-BLUE","price":2250.0,"currency_code":"USD","in_stock":true},{"title":"Heavy (180-220 lb) \/ CMX - Drop Clamp \/ Black","offer_id":60933164663070,"sku":"430-99-014-HEAVY-02-DROP-F43-775X220-ERIDEPRO-SR-BLACK","price":2350.0,"currency_code":"USD","in_stock":true},{"title":"Medium (140-180 lb) \/ CMX - Drop Clamp \/ Blue","offer_id":60933164695838,"sku":"430-99-014-MED-04-DROP-F43-775X220-ERIDEPRO-SR-BLUE","price":2350.0,"currency_code":"USD","in_stock":true},{"title":"Heavy (180-220 lb) \/ CMX - Drop Clamp \/ Blue","offer_id":60933164728606,"sku":"430-99-014-HEAVY-04-DROP-F43-775X220-ERIDEPRO-SR-BLUE","price":2350.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0738\/7548\/9054\/files\/eride-pro-sr-sirris-f43-cmx-fork-front-view-with-gold-stanchions-and-black.jpg?v=1794246065","url":"https:\/\/factoryz.co\/products\/f43-cmx-tune-tool-free-lsc-220-mm-travel-e-ride-pro-sr","provider":"FactoryZ","version":"1.0","type":"link"}
