Genuine-Style M6x35 Flange Bolt for Royal Alloy GT150 and GP300S Scooters

This M6x35 flange bolt is made to hold the starter motor firmly in place on Royal Alloy GT150 and GP300S scooters. It contributes to the engine assembly and helps the engine run reliably. You can find it alongside other Royal Alloy scooter components when you are carrying out maintenance on your scooter. Its exact dimensions are what allow it to seat properly and keep the engine working as intended.

Build and Purpose
