Solo main spring (Yellow; Blue)
Standard yellow-blue coded main spring for the Triumph telescopic front fork leg.
This is the solo main spring for the Triumph telescopic front fork, listed in the parts books as the yellow-blue coded spring. It's the coil spring that lives down inside each fork leg, taking the up-and-down load every time the front wheel hits a bump, and returning the leg to ride height afterward. The color coding (yellow, blue) is how Triumph marked spring rate variants right on the coil so the parts counter and the mechanic could tell them apart at a glance without measuring anything.

In the old parts books this one also shows up under the number H1891, same physical part, just the earlier catalog numbering. It turns up across a number of fork figures in our records, spanning telescopic front fork listings as well as swinging fork and suspension entries, which tells you this spring saw long service across the range of fork figures it's cataloged under.
Fork springs get replaced in pairs more often than not since both legs see the same use, but we don't have a note in our records requiring that here, so buy based on what your fork actually needs. If you're not sure whether your bike takes the standard yellow-blue rate or one of the other coded variants, bring in your old spring or give us a call before ordering.
