Knee Sliders Explained: What They Do and When to Replace Them

Knee sliders look like a small detail until you're the one leant over mid-corner without them. Here's what they're for and when to actually replace a set.

What they're for

A knee slider gives you a reference point for how far you're leant over, and it protects the knee panel of the suit from wearing through on the exact spot that touches down most. Without one, that part of the leather takes direct contact every time you get a knee down, and it wears fast.

Do you need them for road riding

Not really, no. Sliders are built for track use, where knee-down is a normal part of cornering. On the road they're mostly just there because the suit came with them. If you're doing your first track day, they're worth paying attention to rather than ignoring.

When to replace them

Once a slider's worn flat or through to the backing on one side, it's done its job and stopped doing it properly. A heavily worn slider gives you less accurate feedback about your lean angle, and eventually leather starts taking the contact instead. Check them after any session where you were getting a knee down consistently, not just after a big get-off.

Fitting new ones

Most sliders attach with rivets or screw fittings through the knee panel, which means they can usually be replaced without sending the whole suit back to us. If you're not sure whether yours are original Motorce fittings or need the panel itself looked at, it's easier to book in with us than to guess.

Every Motorce race suit comes with external knee sliders as standard, sized to your build the same way the rest of the suit is.
