Motorcycle Apparel Sizing & Return Policy
To ensure the best fit, please carefully review our sizing guide before ordering.
Do not assume your usual size based on other brands, as sizing can vary significantly between manufacturers. Measure yourself using a tailor’s tape and refer to our size chart to determine the correct size. Avoid delays in wearing your gear by ensuring the right fit before ordering.
Return Policy
Once tags have been removed or the item has been worn on a motorcycle, it cannot be returned. We strongly recommend keeping all tags attached and trying on the gear indoors or sitting on your motorcycle to ensure a comfortable fit before use.
We feel this is the only way to 100% guarantee that the riding and protective gear you purchase from our store has not been compromised in any way.
Following these guidelines will help ensure the best fit and a smooth purchasing experience.
We display live inventory for in-stock items. However, due to demand and sizing options, popular 4SR products can sell out. These items are restocked in our bi-weekly orders. If an item is out of stock, it can still be purchased and will arrive with our next order, typically within 2–3 weeks (excluding holiday periods).

The internet provides many options. Not all are good. HHR provides top notch customer service and the best parts available.
quick shipper
awesome customer service
I ordered Avio fiber glass fairing and all necessary brackets for 2023 Yamaha r1. HHR answered all my questions by email and later by phone. The staff I communicated with were knowledgeable, straightforward, helpful, and non-judgmental. I've had been using the products for more than a year, and I have no complaints and am quite happy with it. I've heard it's easy to installl, too, but I had someone else do it, so I can't say if that's true. The bodywork has cutouts for the tail light and headlights. Works great.
