- Triumph America and Speedmaster (all versions 2001-2016, 790/865cc)
Our "bellmouth" intake bracket is a direct replacement of the original restrictor, a change-over that only takes a few minutes but will give your engine up to 32% more air (the opening is 56x81 mm against 48x73 mm from the factory). This is the easiest way to give life to your bike without getting into removing the airbox (see our KIT002 kit).
"Bellmouth" in cast alloy, hand-polished then anodized black for a durable finish.
We recommend also to a "performance" air filter, see our refs KN9004 (Bonneville, Thruxton, Scrambler) and KN1610 (America ou Speedmaster). Please note on America and Speedmaster : the filter is vertical in the bike and the bellmouth increases the risk of water entry in heavy rain or jet-wash situations. We only recommend it for "dry use" !
Carburetor bikes : slightly bigger jets will help towards better engine breathing, see our part number NHY011) for details.
EFI motorcycles : the engine management system will recognize the increased air supply and adapt its parameters. If the rest of the bike is standard, no need to change the mapping, you will get slightly increased performance.
12 month warranty.
Montage simplissime sur ma Newchurch, beau bruit "rauque" d'aspiration bien présent au ralenti, démarrage à chaud facilité, mais peu de ressenti d'amélioration des performances (pots TOR installés) même après modif de la cartographie ; consommation sans changement.
