I've had maintenance performed on 2 Kawasaki sport bikes over the course of several years. The work has ranged from routine tire and drive chain replacement to more substantial suspension repairs. In each instance I have been consistently pleased with the outcome in terms of the initial estimate relative to the final cost of repairs --always coming in under what was initially quoted.
The staff are always attentive and genuinely interested in providing guidance that I have personally found to be useful as a relatively new, mature rider --be it advice on riding gear, performance modifications, or do-it-yourself maintenance.
