Johnston Motorsports in Lakeside is an off-road-only repair facility on Pueblo Road, specializing in side-by-side and UTV service for Polaris, Can-Am, Honda, Kawasaki, and Yamaha platforms. Suspension upgrades pair with the aftermarket shock tuning and valving expertise at Suspension101 in Alpine, extending the local off-road support network from trail-ready setups to race-prepped long-travel kits. A factory-trained technician with fifteen years of powersports experience handles scheduled maintenance, engine rebuilds, and complete ground-up custom builds by appointment. Clutch-kit replacements, belt-tension adjustments, and CVT recalibration address the high-wear drivetrain components specific to desert and dune riding at venues accessible from nearby El Capitan Reservoir and Cleveland National Forest staging areas. Motorsports equipment repair for trailers, portable generators, and support-vehicle systems runs parallel to the broader equipment-service scope at Alpine Motorsports And Equipment Repair on Alpine Blvd. Race-prep builds include portal-gear lift installation, roll-cage reinforcement to SCORE International specification, and turbocharger kit fitment with auxiliary fuel-system calibration for RZR and X3 chassis.
