Bring your classic Triumph 650 T120 Bonneville back to proper breathing with this complete air cleaner assembly for 1963–1966 models, replacing original airbox part numbers 70‑5262 and E5262. Designed as a direct fit for unit 650 twin frames, this assembly restores factory‑style filtration and intake performance on your vintage Bonneville.
Many original airboxes are rusted, modified, or missing entirely after decades of use and aftermarket conversions. Installing a correct air cleaner assembly ensures proper carburetor support, maintains stock intake tract length, and helps keep dirt and debris out of the engine. This is especially important on road‑ridden bikes where reliable filtration directly impacts engine life and performance.
The complete air cleaner assembly includes the main airbox body and internal filter housing components as supplied, ready to bolt onto your Triumph 650 T120 with standard hardware. It is suitable for stock dual‑carb setups and works with original side panels and frame mounting points on 1963–1966 Bonneville models. Ideal for restorations, rider‑quality builds, or converting a bike back from individual pod filters to the factory airbox.
For best results, pair this air cleaner assembly with fresh filters, correctly jetted carburetors, and proper intake rubbers to achieve smooth fueling and consistent performance. Always verify fitment against your Triumph parts book to confirm that 70‑5262 / E5262 is specified for your year and model, and check that all related brackets and hardware are in place for secure mounting.
