Motorcycle repair: what to know

What the job involves, what changes the price, and what to ask a pro.

What motorcycle repair is

A mechanic diagnoses and services motorcycles, handling engine tuning, brakes, the chain or belt, tires, electrical issues and routine maintenance. You need it when the bike runs poorly, a warning light appears, the chain is worn, or the brakes need attention.

Signs you need it

  • The engine runs rough, stalls or loses power
  • The chain is loose, stiff or shows visible wear
  • The brakes feel soft, squeal or pull to one side
  • The battery or the charging system fails or lights flicker
  • The tires show uneven wear or are past their age

What the pro does

  • Reads codes and inspects the engine, the chain or belt, and the brakes
  • Tests the electrical system and the charging output
  • Explains the faults and gives a written estimate with parts and labor
  • Services or replaces the worn parts you approve, such as the chain, sprockets, tires or filters
  • Road tests the bike and checks the repair before returning it

What changes the price

Every job is different, so we do not publish prices. These are the things that move the quote up or down.

  • The make, model and engine size, and how much it must be disassembled
  • Whether the work is routine maintenance or a repair with more labor
  • Whether the bike is a common model or needs specialty tools
  • Whether the brakes, the chain or the electrical system are involved
  • Whether the parts are original, aftermarket or used
  • Whether the bike must be shipped or towed to the shop

What a written quote should spell out

  • The services and the parts used, with brand and grade
  • Labor for each job, listed separately
  • Fluids and consumables used, such as oil, filter and brake fluid
  • Warranty for the parts and labor
  • Any worn parts recommended but not replaced, and why

Questions to ask before you hire

  • Which parts are worn, and what measurements did you take?
  • Do you use the right parts and fluids for my model?
  • Will you road test the bike after the work?
  • Can you show me the worn chain, pads or tires?
  • What warranty do you give on the repair?
  • What should I check myself before the next ride?

Red flags

  • Says the brakes are unsafe without showing the wear or measurements
  • Recommends a full service when only one item is needed
  • Will not put the parts and labor in writing
  • Uses a chain or sprocket set that does not match the bike

What you can do yourself

You can check the chain tension, tire pressure, tread depth against the owner's manual, and keep a service log. Do not work on the brakes or the fuel system yourself, since a mistake can cause a crash. Hire a mechanic for any brake job, any fuel system work and any electrical fault you cannot trace.

Licenses and permits

A license is usually not required for motorcycle repair. Auto repair rules differ by state and city, so check with your state or local licensing agency and ask the shop to show any registration it holds.

Motorcycle repair questions

How often should I change my chain?

Check the chain wear and tension regularly. Replace the chain and sprockets together when they show wear, as a worn sprocket can wear out a new chain.

Why do my brakes feel soft?

Air in the lines, old fluid or worn parts can cause it. Stop riding and have the brakes inspected before you ride again.

Do I need the dealer for service?

Not always. A qualified independent mechanic can handle many services, but ask about training on your model and the parts they use.
