This Jitsie air filter box cover bolt replaces the original steel M8 hex bolt on the Beta Sincro air box cover with a CNC machined aluminium alternative. The design integrates the bolt and collar into a single piece and features a Torx T25 head — the same size used on the rear mudguard bolts — allowing the entire rear section of the bike to be serviced with one tool.
The low-profile head also sits neatly flush in the cover, helping prevent mud and debris from collecting in the recess around the bolt.
