If you don’t keep your bike properly serviced and maintained, worse things can happen than being stranded at the roadside. With none of the stability or safety margins of a car, the results of a mechanical failure can be unforgiving.
In any case, a well-maintained bike is more enjoyable to ride and better protects your investment.
There’s bound to be a specialist motorcycle mechanic near you. The choice boils down to main dealer servicing - essential when your bike is new to preserve your warranty - or an independent specialist.
Your best option for the latter is to look in the Yellow Pages online or rely on a recommendation. Also look for MTA accreditation.
