Pro Circuit – R-304 Shorty Silencer

The Pro Circuit R-304 Shorty Silencer is built for riders who live wide open. Designed for closed-course racing, this compact silencer gives your two-stroke instant throttle response, stronger midrange punch, and that razor-sharp “factory” sound that makes every twist of the grip feel electric. When every second counts, this is the setup you want bolted to your bike.

Built from a 6061 T6 brushed aluminum body with a 304 stainless steel intake tube and end cap, the R-304 is lightweight but tough enough to handle serious moto abuse. The E-Glass internal packing lasts longer and keeps performance consistent, while the allen-head screws make repacking quick and easy. Each silencer is TIG and MIG welded by hand in the USA for maximum strength and reliability. With its short-can design and double-walled mounting bracket, the R-304 is pure race tech — all business, no fluff.

Why We Like It:
It gives your bike that crisp, explosive snap off the throttle that makes racing fun. The sound is clean and sharp, the power hits instantly, and the build quality feels straight out of a race shop.

Why It’ll Work for You:
This silencer helps your bike rev faster and pull harder through the midrange, giving you more control when you need to accelerate out of corners or over jumps. It’s lightweight, durable, and easy to maintain, so you get more performance and less downtime between motos.

Variants / Options:
Available for a wide range of two-stroke models. Designed for closed-course and race use only.

REALLY unsafe to walk around in these
Size: 2 pairs black L
They do what they are expected to do, but should only be used if you are stationary. The gel base makes for very unstable footing if walking around

These work
Size: 2 pairs black L
My husband loves these they help his very dry feet. As others have stated they are extremely difficult to walk in so have to be careful but they do work nicely.

Potential Fall Risk
Size: 2 pairs black L
While these socks do indeed help soften rough skin on your feet, there is a risk of falling while wearing them. Although they have treads on the bottom, which would indicate they’re safe to wear with nothing else, when you put moisturizer on and then wear them your foot can slip inside the sock . This causes you to lose your balance and fall, which happened to me. I’ve thrown them out.

I could be a foot model now!!!
Size: 1 pair black L
I wear work boots almost all of the time so I bought these to put on my feet with salycylic acid to moisturize and try to get rid of a stubborn corn on the ball of my foot. It helped drastically after a few nights of lounging in the house with them on.

Works for foot psoraisis
Size: 2 pairs black L
Got these for work (service industry) to reduce issues with psoriasis and blisters while putting on 20k+ steps a day. Over time the wounds healed and I could work without so much pain. I now don't use them all the time like I used to, only when a new lesion or blister appears, too prevent a breakout. Tip: if you're not in full breakout, wear thick socks under these as a barrier to friction.
