Strong, reliable and good performace, but costly to buy and expensive to keep the tank full. Use of different shims in the KIPS linkage will double the powerfrom 12 to 24bhp and futher tuning can take this to 30bhp at the expense of reliability. More often crashed than seized and popular with thieves, so budget for some good chains,locks etc. Look out for rear disc seizure,loose chassis bearings,monoshock wear and electrics. KDX version has full-on enduro styling from 1990-94.
