The KX450F’s aluminum frame carries a Showa SFF-Air Triple Air Chamber (TAC) fork, which works well enough but requires setting air pressures separately in inner, outer, and balance chambers. (Not to mention tire pressures! Bring your air pumps…) The shock is plush and keeps the rear end nicely planted in tough conditions. Ergonomically, the big Kawi excels, with a slender overall build that lets the rider move about freely whether bombing to the first turn, weighting the front end while cornering, or airing it out over jumps. Like the KX250F, adjustable handlebar mounts and footpegs help tailor the bike to taste.
