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).
Are you into black? Want the highest level of safety? Than look no other way, we've just the thing for you! Black classic in a two-piece design ready for an airbag. In our new leathersuit you can enjoy both performance riding on the race track and the casual afternoon ride in jeans.
The materials, cut, and triple-stich sewing technique are based on our experience developing racing suits. At 4SR we do not differentiate between racing and customer suits, so this suit is made of the same quality leather, sewn with the same technology and equipped with the same protectors as the suits of our factory riders in WSBK, BSB or Moto America.
The leathersuit is made of premium 1.2 mm thick cowhide leather and comes equipped with a total of 17 protectors. On the shoulders, elbows, knees and shins you will find comfortable Italian Betac protectors. Panels of memory foam sewn into the areas around the shoulders, collarbones, elbows, forearms, hips, base of the spine, knees and shins, absorb impact during falls and give another level of protection in case the leather is sanded trough. The most exposed areas during falls – shoulders, elbows, buttocks and hips – contain extra layer of leather. All this is complemented by black sliders on the shoulders, elbows and knees. The suit can be equipped with a back and chest protector, or one of the airbag vests available on the market.
The pre-curved sleeves, forward-leaning shoulders, well-shaped knees, and seamless stretch in the crotch and underarms allow for a flawless riding position on a sportbike. The narrow sleeve cuffs do not impede wrist movement and allow the use of racing gloves. For greater comfort, the jacket is extended in the back part and can be easily attached to kevlar jeans or leather pants using long or short zipper. The suit is embroidered with 4SR logo and other decorative elements made of suede leather.

One of the best purchasing experiences I've had. Customer service and communication is excellent.
They're a little tricky to install if you leave the radiator on the bike, but doable with minimal tools. The fit and finish can't be beat.
professional and very nice conversation and customer service even i did some mistake and they fix it
thank you 🙏
Very happy with the shock. HHR was great!
Easy fast and what I wanted
Love it, wish it came in twill weave gloss but it is on sale and fit and looks amazing! Just ordered frame carbon fiber from here as well to match !
I ordered this part for my r6.
Got a email back about 4 days later saying I didnt order the correct lines for it.
HHR didnt have to do that. I would not have known they took the time to make sure i got the part the first time.
I appreciate that alot. Integrity in this day and age seems to be long forgotten thing.
Will be ordering more parts as I need them and will use HHR for them.
Awesome piece and fits perfect. Definitely recommend getting this over the standard version, which I also have. This one pan is 30mm lower. Also make sure you get the Alpha seat Support bracket if running the stock subframe in addition to the mounting kit.
8mm swingarm spools such a great design very strong and doesn’t weigh nothing there not so big so it doesn’t stand out it’s perfect
Great experience
Does what it's supposed to do
