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).
Airplanes and motorcycles have always had a lot in common – passion for speed, touch of freedom and sense for adventure. The Bomber Jacket Brown Patina leather jacket combines the cut of flight jackets, motorcycle design, modern materials and a great deal of style.
Original in every inch
Bomber Jacket Brown Patina by 4SR is a jacket primarily designed for motorbike riders. However, thanks to the thin and soft premium leather it is also suitable for leisure and casual wear. Just remove the protectors. The jacket is made of lightly waxed buffalo leather. It's natural pattern gives every single product a unique look, therefore you will not find two identical pieces in the entire collection. Only you will wear a single and unique original!
Safe
Because rider's safety is a priority for us at 4SR, the Bomber Jacket Brown Patina is equipped with top-notch Safe Tech (Level 2 T+ certification) protectors in the shoulders and elbows. These protectors are very well designed so you won't even know they are there. A spine protector can be inserted into the jacket as well.
Practical
Elastic ribbed cuffs on the sleeves and waist gives more comfort to wear and protect the rider from drafts. The jacket can be combined with kevlar jeans and leather moto pants using a short or long zipper. A total of six pockets are available for necessary small items – three external and three internal. All outer pockets can be closed with a YKK zipper in Gun Metal finish.

The higher pressure cap stopped my overflow from becoming pressurized and blowing out. I did a combustion gas test on the cooing system and it passed all 3 times, so it made since the factory cap was to low of a rating for serve duty.
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.
