Sidecar main spring (Yellow)
Yellow-coded front fork main spring for 1964 6T, TR6, and T120 telescopic forks.
This is the main fork spring listed for the telescopic front fork on the 6T, and separately for the TR6 and T120, marked out in yellow for identification. Front fork springs on these machines come color-coded so the correct rate can be picked out at a glance in a bin of otherwise similar-looking springs, and "yellow" here is the catalog's way of flagging which one this is. The older book number for this part is H1697, if that's what's printed in your parts manual.

It sits down inside each fork leg and does the basic job any fork spring does: it supports the weight of the front end and controls how the leg compresses and rebounds over bumps. The catalog ties this part to 1964 fork assemblies on the 6T, TR6, and T120, so if your fork internals are from a different year, check that the spring rate and length actually match what's currently in your legs before ordering.
We don't have extra detail on this one beyond what's in the parts book. Call the shop and we'll confirm fitment against your fork setup before you order.
