Published: 21 August 2008

Updated: 21 November 2014

Triumph tuning specialist Norman Hyde has developed a new High-Flow Intake Bellmouth system for the Triumph Bonneville.

The solid aluminium bellmouth fits to existing fittings and mounting points and improves air-flow to increase power and torque throughout the rev range.

By combining the intake with the Hyde Bonneville Classic silencers, peak power can be raised by up to 6bhp, and torque by over 17%.

The bellmouth costs £90. Call 01926 497 375 for more information.
