Mustang Reborn: California Scooter Company

It was a bad one as motorcycles accidents go, and my recovery was a lengthy one.  A friend contacted me and asked if (while I was recovering) I’d like to write Internet responses to the keyboard commandos badmouthing a company making a new Mustang motorcycle.  Would I ever…and that’s how I hooked up with CSC Motorcycles and the modern Mustang.  The story is fascinating.  Here’s a bit of it, which appeared as a sidebar to my Motorcycle Classics Mustang article.


Ed Seidner founded one of the largest motorcycle superstores in the country, Bert’s Mega Mall in Covina, California, which today sells new Hondas, Ducatis, Triumphs and more. Son Steve ran that operation until he branched out on his own, starting motorcycle accessory company Pro-One Performance Manufacturing.

Ed never had a Mustang, but his friend Billy Buster had one when they were kids and Ed always wanted one. Steve grew up hearing stories about Billy Buster and his Mustang, so he decided to do something about it. He bought an unrestored 1954 Mustang on eBay and took it home to the Pro-One production facility to restore it, a surprise gift for Ed. Steve quickly discovered three things: Customers walked right past ultra-sleek Pro-One V-twins for a better look at the unrestored Mustang, the Mustang was
a simple design, and the little bike was solid. In fact, after Steve drained the stale gas, cleaned the fuel lines and filled the bike’s peanut tank, the old Mustang started on the first kick.

Steve’s response was swift. With the 56-year-old Mustang as a template, he started California Scooter Company (www.californiascooterco.com), making the bikes he believes Mustang would build today. The new CSC motorcycles are EPA and CARB approved with modern amenities like electric start, turn signals, speedometer, hydraulic disc brakes, etc.

The bikes are built in La Verne, California, about 30 miles from the original Mustang factory, while the engines are sourced from Asia. Three years after introducing the 150cc CSC 150, CSC introduced the 250cc P51, taking the P51 designation from the World War II Mustang airplane. With its larger 250cc counterbalanced single overhead cam engine, the P51 absolutely rips. The Mustang formula — short wheelbase, light weight and 12-inch wheels — still works.

So how does the new compare to the old? Fully broken in, my 150cc red CSC Classic tops out at about 66mph. With their 320cc engines, the original Mustangs were crazy fast. My geezer buddies tell me a stock Mustang would do 70mph (how they knew that is beyond me, as Mustangs didn’t get speedometers until the late 1950s). I’ve touched 80mph on the new P51.

I’ve ridden vintage Mustangs, but because of their value I was afraid to push them too hard. The old Mustangs feel a little wobbly to me, but of course they have old forks and old tires. The new bikes benefit from more than 50 years of advancements in technology. When I take my CSC on Glendora Ridge Road, the bike is light, tight and an absolute delight through the twisties. Which bike is faster or better is moot. Both are awesome, and each offers a riding experience like no other. There’s one fact, though, that riders of vintage Mustangs and new California Scooters both have to accept:

As I mentioned in the prelude to this blog, when I wrote the Mustang story for Motorcycle Classics magazine I was also a consultant to CSC Motorcycles.  CSC Motorcycles stopped producing Mustang replicas a few years ago (around the same they started importing the advernture touring RX3), so there are no more new California Scooter Mustang replicas.  But the modern Mustangs do come up for sale now and then, and the best way to find one is by contacting CSC directly. If you’d like to know more about CSC, their Mustang replicas, and how the company became the North American importer of Zongshen motorcycles, you should pick up a copy of 5000 Miles At 8000 RPM.

  1. I am planning to re read 5000 miles at 8000 RPM next week… what great adventure. Thanks for reminding me! As for the Mustang CSC version there was guy down here in Florida that had one for sale. I emailed him about coming up to see it, about 30 miles or so in New Port Riche, but when he emailed me back he said it was sold to an undisclosed buyer, what ever that means? I do look at Craigslist occasionally and the tip about contacting CSC is good one, I may just do that. As a kid growing up in the last century the Mustang was one of the very very cool things that California kids had and we Mid-Westerner’s could only dream of such wonderment! Now that I am a little older maybe buying a Mustang with all the wonder is comes with plus new modern motor, brakes, tires, and chassis makes a little more sense. Thanks for sharing!

  2. Great article and awesome little motorcycle. I enjoyed riding the 250cc you guys had just gotten in.

    1. I need to find that video I did when we were up there. In the meantime, here’s a build video of the bike Steve did for In-N-Out Burger:

  3. Correction .
    Mustang gas tanks are what they are.
    Mustang tanks. Mustang tanks were popular on choppers. Many aftermarket tanks are around and if they actually fit the profile of the originals can me billed as a mustang tank . But I would imagine a true Mustang tank to be valuable not just for a mustang restorer but period choppers as well.
    Now idk exactly what tank was in the old mustang your friend restored . But if it was original it wasn’t a peanut .
    Despite Harley stealing the jargon and others that think a peanut tank is a 2.2 gal sportster tank . It’s not .
    Sportsters got the Harley hummer tank.
    Peanut tanks look like a shelled peanut nut. Originally used on hill climbers and other race bikes where gas volume ( often 1.8) wasn’t an issue.
    Most often supplied by Wassel .
    These became popular for chops.
    Being a straight moto press guy I suppose you wouldn’t know. And again , maybe your pal did have an aftermarket Wassel peanut on his bike.
    But this is a history spiel I couldn’t resist posting . I am afraid when the old timers are gone so is the true history of these tanks. I like the neo mustang despite the Chinese engine. So be it.
