If you wish to perform adjustments for your Bimota Mantra then it is usually a great idea to have access to a Workshop Manual to use as reference if perhaps you want to know tips on how to take out a specific component for example, the Brake Discs and match it again accordingly.
Bimota Mantra Workshop Manuals will give you certain diagnostic info on your car therefore if something is wrong it can help you figure out what the situation is and the best way to resolve it. After that you can analyse if this can be achieved yourself or in the event the job is just too big you can make a reservation for your Mantra into a trusted mechanic.
