Motorcycles
Street, sport, cruiser, and touring motorcycles — oil, brakes, tires, inspections, and diagnostics.

The same Frederick shop that maintains cars and trucks also services powersports — including motorcycles, sport bikes, cruisers, touring bikes, scooters, ATVs, UTVs / side-by-sides, dirt bikes, dual-sport, and off-road machines. Repair and inspection only. We do not sell motorcycles or ATVs.
Renn Kirby Frederick Auto – Powersports Service
Cars. Trucks. Motorcycles. ATVs. UTVs. And more.
Renn Kirby Frederick Auto is expanding the service department so riders and off-road owners in Frederick, MD have a local shop for maintenance, inspections, and repairs. This is not a powersports dealership and not an inventory page. We do not buy, sell, or take trade-ins on motorcycles, ATVs, or UTVs.
We service more than cars and trucks. Vehicles we work on include motorcycles, sport bikes, cruisers, touring bikes, scooters, ATVs / four-wheelers, UTVs / side-by-sides, dirt bikes, dual-sport, off-road, and other similar machines. If you do not see your machine listed, send us the information — availability still depends on the specific vehicle, make, model, and repair.
Need Rough Country parts installed on a UTV or ATV you already own? That is a separate accessory-install program. This page is for service, inspection, tires, brakes, fluids, and mechanical work on the unit itself.
