If you choose to perform maintenance tasks to your Keeway Speed 150 then it is always recommended to have access to a Workshop Manual to keep just for a reference if perhaps you need to know tips on how to strip off a particular part for example the Wheel Bearing and install it again properly.
Keeway Speed 150 Workshop Manuals provides specific diagnostic guides on your vehicle therefore if something is broken it can help you figure out what the issue is and the best way to make it better. After that you can analyse if this can be done on your own or in the event the job is too big it is possible to make a booking for your Speed 150 into a nearby garage.
