Questions To Ask Before You Hire
Do I need a specialist for a Triumph Bonneville build?
For light bolt-ons, a strong general performance shop may be enough. For fabrication, wiring, tuning, bodywork, or full custom work, choose a builder with platform-specific experience or closely related builds in their portfolio.
Should I buy parts before contacting a shop?
Usually wait. Shops often have preferred parts that fit better, carry a warranty, or save labor. Buying the wrong kit can cost more than the discount you found online.
What makes a quote more accurate?
Photos, a clear build goal, current issues, preferred style, target budget, and how you plan to use the Triumph Bonneville all help a shop price the work realistically.
