If you wish to conduct maintenance tasks on your Triumph Street Triple then it is always recommended to have a Workshop Manual to use as personal reference if you need to know how you can take out a specific component such as the Wheel and install it again successfully.
Triumph Street Triple Workshop Manuals offers you distinct diagnostic info for the car or truck so if something is not working it can help you understand what the situation is and ways to make it better. After that you can analyse if this can be done on your own or if the job is too big you could make a reservation for your Street Triple right into a nearby repair garage.
