HIGH GEAR 5 SPEED NO BEAR
Bare high gear for a five-speed Triumph gearbox, sold without its bearing.
57-4780 is the high gear for a five-speed gearbox, sold bare, meaning no bearing fitted to it. In the mainshaft cluster, high gear is the top ratio and this is that gear on its own, without the bearing that normally rides with it.

Because it's listed bare, plan on sourcing or reusing the correct bearing separately when you put the gearbox back together. We don't have more detail on this one beyond what's in the catalog entry, so if you're not certain this is the exact gear your box needs, call the shop and we'll help confirm fitment before you order.
As with any internal gearbox component, take a look at the mating parts (selectors, bushes, the mainshaft itself) while you have things apart, since wear tends to show up together.
