SATO RACING - Made in Japan

SATO RACING is the international brand identity for BABY FACE Inc. Founded in Osaka, Japan in the 1980's by Katsuhiko 'Babyface' Sato, BABY FACE started out building race bikes. By the late-'90's the company was making a name for itself fabricating ultra-lightweight titanium exhaust systems and other specialized racing parts. Sensing there would be strong demand for the company's premium quality racing parts outside of Japan, Mr. Sato decided it was time to expand internationally. By 2001, a US distribution warehouse was established in California, and exhaust systems made by his company were being regularly imported and sold under a new brand name, SATO RACING.

SATO RACING Titanium Exhaust Systems were an immediate hit with trackday racers and custom bike builders alike, and the performance and design aesthetics of these exhausts helped to build a prestigious reputation for the SATO RACING brand in the US and beyond. Other exciting and innovative parts such as billet aluminum Rear Sets soon joined the product lineup, along with less exciting but equally vital racing parts such as Frame Sliders, Axle Sliders and Swingarm Spools.

By the end of the last decade, rising costs of titanium, along with stricter motorcycle noise regulations in Japan and elsewhere meant the party was ending for makers of unrestricted racing exhaust systems, and a decision was made to phase out production of exhausts and instead expand development and production of the other racing parts the company was known for. Although fans of our exhaust systems were disappointed, in the long run this proved to be a wise move, as the company has done very well selling its other (non-exhaust related) parts, not to mention competition in the exhaust field has become increasingly crowded with high quality alternatives in the years since we ended production.

Today, CNC-machined billet aluminum and Delrin-based parts, such as Rear Sets, Sliders and Racing Hooks, account for most of our production output, and have helped us maintain a loyal fanbase due to their high quality, refined styling and superior performance, much like our exhaust systems had in the formative years of the company.

Our engineers now take full advantage of the emerging 3-D scanning and printing technologies to prototype parts. Our state-of-the-art 3-D printers can output fully functional parts in a matter of hours that are durable enough to be installed on a motorcycle for testing, making it much easier to get the design of part just right before committing to CNC machining the final version of the parts out of billet aluminum. This greatly streamlines a process that used to take weeks of trial and error, bringing down the development time substantially.

SATO RACING - Made In Japan
Early on, when we were making parts primarily for the 'Big 4' Japanese brand sportbikes, our slogan 'Made in Japan' was adopted as a way to help our limited-production, handcrafted racing parts stand out from the cheaper competitng brands of motorcycle parts being mass-produced in China and elsewhere, while at the same time embracing the uniquely Japanese 'JDM' design aesthetics of our parts. Even today when many of our most popular parts are increasingly for very non-Japanese bike brands such as BMW or Harley-Davidson, we still kept the 'Made in Japan' slogan as a way of making it clear that our parts were primarily designed by, and for, racers in Japan, who have there own distinct needs when it comes to racing parts. As a result, some of the parts we sell might seem a bit unusual to riders outside of Japan. But since our parent company's primary market is Japan, it has never been a priority to try to 'design by committee' to cater to the tastes of riders in the US or other countries. And we believe our parts are all the better for it.

It is important to emphasize that this slogan is not meant as a snub to all the great companies proudly manufacturing parts in the USA. We make no claims that our parts are superior because they originate from Japan, only that they are uniquely Japanese in design, with all the pros and cons that go with that.

parts are developed and tested with the assistance of circuit racers in Japan. Our parent company's HQ is not too far from Suzuka Raceway, which has led to many specialized racing parts being developed for the All-Japan race series and teams entering the yearly Suzuka 8 Hours endurance race. From 2015-18, our engineers were heavily involved with the Hooters Japan team, but many other teams also use our parts. Team Kagayama has used our Rear Sets and Frame Siders on their podium-finishing GSX-R1000 for several years, and in the 2015 race alone over half the entrants were using at least one part made by BABY FACE / SATO RACING. Many of the one-off prototype parts initially developed for racers entering the Suzuka 8 Hours end up being put in production later on, most notably our 'Race Concept' series of racing parts, so this race was and continues to be an important testbed for our parts.

SATO RACING 'Race Concept' Racing Parts
Due in part to heavy interest in the one-off racing Rear Sets our engineers have been designing specifically for teams participating in Suzuka 8 Hours and the All-Japan endurance race series, in 2014 we introduced our Race Concept series of Rear Sets. These Rear Sets are pure racing-spec Rear Sets designed for dedicated track bikes, with no design compromises to make them also compatible for street use.

Compared to our standard Rear Sets, which often have a limited range of positions in order to maintain compatibility with the stock brake switch and ABS, our
Race Concept Rear Sets are able to provide a much more aggressive range of positions. This track-optimized design means there is no built-in compatibility with the stock exhaust hanger, brake light switch / ABS on most models.

We are the first to admit our
Race Concept Rear Sets are not for most riders, but if you are building a full-on race bike, these may be exactly what you are looking for to get an edge over the competition.

In addition to Rear Sets, we have been expanding our lineup of
Race Concept series parts to include other categories such as Clip-on Handle Bars.

Around 2010, SATO RACING entered into the field of carbon composite parts. A state-of-the-art autoclave was obtained, and premium quality dry carbon was sourced from the same company that makes the carbon used in construction on the Boeing 787 Dreamliner. The first few years of carbon parts production was promising, and over 60 unique carbon parts were eventually designed and produced, ranging from engine covers to rear fenders and swingarm covers. But by the end of 2014, technical difficulties combined with excessive production costs conspired to prematurely halt the production of most carbon parts, with the exception of a few one-off and limited-run parts for race bikes. ( Click here to see our remaining inventory of SATO Carbon parts ).


Although we carry most of the same parts as our parent company Baby Face Inc. (but with different brand logos), for various reasons certain items listed on Baby Face's Japanese website are not listed on SatoRacing.com, or vice versa.

One reason is that Baby Face sells some parts that are for use with bikes or aftermarket parts that are only sold in Japan, while Sato Racing mainly carries parts for bike models sold in the US or other countries outside of Japan. In some cases we decide not to list a part on our website or import it, either because the part in question is a little too specialized. or the bike model the part is designed for is rare or obscure. (Anyone out there looking for rear sets for a Megelli 250R?).

Another reason is that Baby Face Inc. is a leading Japan distributor for many other brands (including US based companies JE Pistons, Carrillo Pistons and Cometic Gaskets, among others), in addition to making Baby Face / Sato Racing parts, and we only sell the parts actually manufactured by us. But if you see a part at Baby Face that you are interested in that is not listed on SatoRacing.com, we will see what we can do to get it added to our inventory.

( NOTE: Due to brand trademark issues and other reasons, 'Baby Face' branded parts are only sold within Japan. SATO RACING only carries parts with the 'Sato Racing' logo, and cannot special order parts with the Baby Face logo. )

SATO RACING Replacement Parts

Need Replacement parts for your Rear Sets or Sliders? Maybe not today, but the odds are good you will need spare parts in the future. That goes with the territory of riding a sport bike; Most bikes will get dropped eventually, or parts will wear out or vibrate loose and fall off. For this reason, we always keep a large inventory of replacement parts on hand at our California-based distribution center, so you can get your bike back on the road or track quicker than you might expect. If there are any parts we do not have in stock, we can usually get them within 4-5 weeks. We can also answer any questions you may have about repairing the part.

Now celebrating our 23rd anniversary in the U.S., SATO RACING continues to grow and expand, and we are committed to continue supporting all existing owners of our parts to the best of our abilities, along with continually bringing more new and exciting parts to our lineup in the future as new sport bike models are introduced.


Q: How big is Sato Racing?
A: The American side of the company is currently staffed by 2 highly knowledgeable people. The production side of the company in Japan has more people, but overall we are a relatively small, streamlined operation compared to some other parts makers.

Q: Can I visit Sato Racing and buy parts in person?
A: We are in a warehouse with no actual storefront or even a sign, so you may be a bit disappointed, but we always welcome visitors. Our business hours are not set in stone and can vary a lot, so give us a heads up that you are coming so we can make sure someone will be there when you arrive.

Q: Can I bring my bike to Sato Racing for custom parts fitment, or can I loan you my bike so you can make parts for that bike model?
A: We love it when people bring their bikes when they visit us, but we are not set up to do any actual parts designing or fabricating on the US side. That all happens at our HQ in Japan.

Q: Why can't I find Sato Racing parts in the big motorcycle parts catalogs or retail chains like Cycle Gear?
A: We do not make the kind of mass-produced, high volume items that those resellers typically deal with. We are independent, and prefer to sell direct to customers or through select independent parts sellers and motorcycle dealers.

Q: Why do you list parts for sportbike models that are not even sold in the US?
A: We sell parts all over the world. Also, as motorcycle fans, we enjoy learning about all the cool bike models that are rare or non-existent in the US, and we think others do too. Sometimes those non-US models are eventually brought to the US (such as the international Suzuki GSR750 becoming the US GSX-S750, or the Indonesia Kawasaki ZX25R eventually making it here as the ZX-4RR), and we end up in a good position since we are among the first to have aftermarket parts ready for it.

Q: Why does your Online Store only allow shipping to a few countries right now?
A: Many countries make it difficult to ship motorcycle parts to for various reasons. Also, we prefer to calculate international shipping costs manually to give you the best rate and also give you a heads up on any duty/import tax that may be billed to you by Customs prior to delivery. Contact us directly to get a quote for shipping outside the US.

Q: Is the part I want in stock? Or do I have to wait for it to arrive from Japan?
A: If you can buy it in our Online Store, that means it is on the shelf at our US warehouse and ready to ship.

Q: I need a particular part for my rear sets but it is not listed on your website. Do you have it?
A: We probably have it. It would take forever to list every replaceable part in our Online Store, so only some common parts are listed right now. But we try to keep replacement parts for everything in our inventory.

Q: I have been waiting for many months for a part that is not in stock. Why don't you have it yet?
A: Our plant in Japan is a full-time operation, but it can only churn out so many parts at a time, so when we order parts that are not already in stock in Japan, they are then added to the waiting list for the production schedule, but if there is a backup, it may take awhile for the part to actually get produced. Additionally, some specialized parts have a longer wait time than others due to additional prepping and handling involved.

Q: How often do you get parts shipments?
A: We get shipments air-freighted to us once or twice a month.

Q: Why do you have an eBay Store in addition to your Online Store?
A: eBay has always been very useful as an advertising platform, bringing in some new customers who might not have thought of getting Sato Racing products. It also makes it easier for customers in other countries to get our parts, since we can use eBay's International Shipping Program to ship nearly anywhere.

Q: Why are only some Sato Racing items listed in your eBay Store?
A: If you have more than a few hundred items listed on eBay at a time, it becomes difficult to keep track of inventory. We generally only list items on eBay that we have a lot of in stock, so we don't mistakenly sell something we don't have on hand. Also, some parts are just easier to sell on eBay than others. If an item does not sell within a few months, we will rotate it out for a different item.

Q: Why don't you sell more branded apparel and merch?
A: We have plans for a new T-shirt design and possibly some other branded goodies in 2024.

Q: Why don't you have a YouTube channel with hands-on installation videos?
A: That is a dream of ours, but right now there are just not enough hours in the day to do that and everything else related to running Sato Racing. Some independent YouTube channels have made nice videos showcasing our products.

Q: I am a racer who races in competition. Will you sponsor me?
A: We get requests for racer sponsorships on a daily basis, and unfortunately we do not have the staffing or promotional budget to get deep into sponsorships on the US side. The Japan side of the company (Baby Face) is a different story, but so far all their racer support is only within Japan.
