Frequently Asked Questions

The BS3 Silencer is the standard fitment for the Classic 350/500, available in Chrome, Black or a dual-tone finish. If you want a deeper note, the BS3 Riverscone or BS3 Big Pipe are built on wider-diameter bodies for the same bike. All three are bolt-on, direct fit — no modification needed.

Both are the same body and internals — the difference is purely the exterior finish. Chrome is polished for a mirror look and is our most-requested finish for a stock-look bike. Black is a powder coat, which shows less road grime over time. We also make Chrome + Black and Black + Chrome dual-tone options on most models.

Every HKK silencer is bolt-on, direct fit for the bike model it is listed under — no cutting or welding is needed. We recommend fitting by a mechanic familiar with your specific model, since torque specs and clamp order vary slightly between bikes.

Compliance depends on the specific model and your local regulations — confirm with us directly for your bike model and region before ordering if this is a requirement for you.

Most come in all four — Chrome, Black, Chrome + Black and Black + Chrome. A few models (the Angular Silencer, the X3/X4 Design silencers, and the Meteor X2 Design) are made in a smaller set of finishes only — check the specific product page for what’s available.

Silencer bodies are stainless steel. Guards and the chain sprocket are mild steel, black powder coated for corrosion resistance.

No — each bike model has its own mounting geometry at the header clamp and frame bracket, so silencers are not interchangeable across models even when they look similar. Always order the silencer listed under your specific bike model.

Retail customers can order a single piece. Dealers ordering at carton quantities get the tiered dealer pricing — see the specification table on each product for its carton size.

Some parts, like the Classic Model Sari Guard, are used across more than one bike model. "Also fits" links you to the other model page it applies to, so you don’t have to search twice.

Our current range is the models listed on this site. For a custom requirement, contact us directly to discuss.

The Big Pipe version is built on an oversized-bore body for a deeper, lower-pitched exhaust note than the standard silencer for the same bike model. Fitment and finish options are otherwise the same.

Both share the same body — the difference is the length of the styled end-plate at the tip. Choose based on the look you want; fitment is identical.
