Norton Spring, Fork Main
Fork main spring for Norton front forks, catalog part 06-7723.
06-7723 is a fork main spring for a Norton front fork assembly. It shows up in the parts book under Front Forks along with the Steering Lock and Steering Head Bearings figures, which tells you it's part of the front end setup rather than anything downstream in the frame or swinging arm.

This is a Norton part, not a Triumph one, despite what shop you may have found it through. The catalog record we have only ties it to a single model year, so we can't tell you it fits a specific Commando variant or any other Norton model beyond that. If you're matching this against an existing fork leg or trying to cross it to a specific bike, give us a call and we'll go through what we've got together before you order.
As a main fork spring, its job in general terms is to support the weight of the front end and control the up-and-down travel of the fork legs. Beyond that function, we don't have more detail on this one to add.
