Seems like I read "somewhere" our frames are around 15kg, or about 32 pounds naked. If I am recalling that info correctly (not sure at all), then a CF frame would probably lighten thing 12-15 pounds or so. To get our bikes down to 200 pounds MX/MXR, or 220 for the EX/EXR, we would need to re-visit every component......and......go with a smaller battery. Would mind loosing the weight to a lighter CF frame and wheels/rims/tires/tubes selection, but I like the battery and the range it gives me.
