These exhaust pipes are the factory correct balanced type, suitable for restoration of the Norton 850 Commando models.

Genuine UK manufactured exhaust pipes by LF Harris feature top quality chrome plating. These are the correct balanced style exhaust pipes, as used on the 1973 and 1974 850 Commando models.

The exhaust pipes are joined at the outlet stubs with a balance tube, and use special corrugated sealing washers, tab washers, collets, and locking rings.

The exhaust pipes are loosely assembled to the cylinder head with the balance tube in place, then the locking rings are tightened and retained with the tab washers. 

Please note: Due to varying bans on the use of hexavalent chrome in the chroming process, this item will have varying appearance different than OEM standards. Chromers are frequently using trivalent in their processes. “It’s just not the same color. Hexavalent has that clear blue sheen, but trivalent is more grayish and smoky. Trivalent will not replace the look of hexavalent.”


LF Harris motorcycle spares are produced to the highest quality standards possible utilizing original Triumph tooling, dies, factory blueprints & materials combined with modern manufacturing equipment, tolerances & techniques.
