20-642 Tech, Classic handlebar master cylinder. 12mm

If you are building a clean, retro-style cockpit, this Kustom Tech Classic handlebar master cylinder is a beautiful piece of hardware. It is forged from raw aluminum and features a compact, smooth-shaped lever with a finned cover that looks right at home on any vintage-inspired project. The 12mm piston is ideal for smaller calipers or single-disc setups where you want a firm, controlled feel. It includes a glass inspection window for easy oil level checks and has the necessary approval codes printed discreetly underneath. This master cylinder fits 1 inch handlebars and is a great way to get rid of bulky, modern plastic reservoirs in favor of something with real character.
