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 looking for a top-class racing suit to accommodate your standalone airbag vest? Then you’ve just found the best Airbag Ready® leathers on the market. Our latest specification Monster Green AR 1PC race suit comes with all the unique safety points you would expect from 4SR, but with our increased area of accordion stretch panel, this suit can now work safely in conjunction with any standalone airbag vest for racing.
Over the years we have been working with professional racers to develop the safest suits possible, this is our safest and most comfortable yet. Racing Monster Green AR suit already comes with 18 ergonomically placed protectors and if you remove the 4SR Level 2 back and chest protectors, you can then wear your chosen airbag vest underneath. Easy and fast, you're now Airbag Ready!
Thanks to the unique cut and placement of accordion stretch panels, you can use several variants of standalone airbags available on the market. Our stitching and materials remain and will always remain 100% the same as our factory racers suits.
The price includes knee and elbow sliders, internal protectors, removable chest and back protectors, double hip and coccyx protection and all from reputable brands. We have 18 ergonomically placed protectors, the most used in any mass-produced 1pc leather suit.
We have also developed a simple and effective solution for holding up your leathers between track sessions, 4SR's Zipper Lock system will effectively hold the upper half of your suit out of the way.

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
Love the quality and how fast I received my item even being custom ordered
Perfect fit and great quality. The coolent hose clamps are definitely a must due to there perfect sizing
