Swedish Steel: 1975 Husqvarna 400 CR Restomod

For Sale: ’75 Husky 400 Cross — The World Championship Weapon…  

In 1975, Husqvarna stood at the absolute summit of the motocross world. The 400 CR wasn’t just another big-bore two-stroke — it was the platform that carried Heikki Mikkola to the 1975 500cc World Motocross Championship, cementing the dominance of Swedish engineering on the global stage.

On American soil, riders like Kent Howerton proved the bike equally formidable in the AMA Nationals, while earlier Husky 400s had already become cultural icons thanks to Steve McQueen and Malcolm Smith in On Any Sunday.

By ’75, the 400 CR had evolved into one of the most feared open-class motocross machines on either side of the Atlantic. To understand how it achieved that dominance, we have to rewind a few years.

From Desert Racer to World Champion: Evolution of the 400 CR

The 1975 400 CR didn’t appear out of thin air. Its roots stretch back to the late 1960s, when Husqvarna was rapidly establishing itself as a dominant force in off-road racing. The early 400 Cross models — including the 1969 machines that became cultural icons — helped build Husqvarna’s reputation for lightweight chassis design and rugged two-stroke reliability.

Those early bikes were simple, brutally effective desert racers and motocrossers, built around chrome-moly frames and torque-rich piston-port engines that favored tractable power over peaky aggression. Through the early 1970s, Husqvarna continuously refined the platform:

• Improved porting and cylinder design for stronger midrange
• Strengthened crankshafts and bottom ends
• Revised frame geometry for better high-speed stability
• Longer-travel suspension to keep pace with rapidly evolving tracks
• Lighter components to maintain competitive power-to-weight ratios

By 1972–73, the open-class motocross wars were escalating. European manufacturers like Maico and CZ were pushing displacement and power, while Japanese brands were entering the fray with increasingly sophisticated machines. Husqvarna responded not by simply chasing horsepower, but by refining balance — ensuring that their big-bore machines remained controllable, durable, and race-ready straight from the crate.

The 400 CR designation itself stood for “Cross,” distinguishing it from Husky’s WR (Wide Ratio) enduro models. While WR bikes were tuned for woods and long-distance competition, the CR models were purpose-built motocross weapons: closer gear ratios, sharper throttle response, and suspension valved for track use.

By 1975, the 400 CR represented the pinnacle of Husqvarna’s twin-shock development. The engine delivered broad, muscular torque rather than explosive top-end hit. The chassis was slim and light, allowing riders to muscle the bike through ruts and berms despite its open-class displacement. Swedish metallurgy — particularly in the crankcases and transmission components — had earned a reputation for bulletproof longevity.

Importantly, 1975 also sat at a technological crossroads. Monoshock rear suspension systems were beginning to emerge, and within a few years they would dominate the sport. That places the 1975 400 CR at the high-water mark of the twin-shock era — fully developed, fully sorted, and honed by years of Grand Prix competition before the next revolution arrived.

In that sense, the 400 CR isn’t just a fast vintage motocrosser. It’s the final, fully matured expression of a design philosophy that had ruled the sport for nearly a decade.

The 1975 400 CR: What Set it Apart…

The mid-’70s were a golden era of European big-bore motocrossers. The Husky battled machines like the Maico 400/440, CZ 380, Bultaco Pursang 360, Suzuki TM400, and Yamaha’s MX offerings. What set the Swedish machine apart was its blend of:

• Strong, tractable torque
• Lighter overall weight
• Superb metallurgy
• Predictable chassis geometry

At roughly 230 pounds and around 40 horsepower, the 400 CR delivered a ferocious yet controllable powerband. The bottom end was famously durable, while the chassis offered a balanced feel that rewarded skilled riders without punishing the rest.

Twin shocks, long-travel forks (for the era), and Husqvarna’s distinctive silver frame/red tank livery made the bike instantly recognizable.

This Bike: Restored 400 CR Restomod

The example you see here is no mere rider restoration. It was previously owned by Eric Eversole and displayed at multiple AMA Supercross “Legends & Heroes” events. According to Kaplan Cycles, who are selling the bike at auction here, the machine has undergone an 80+ hour frame-off rebuild, blending period-correct aesthetics with modern reliability upgrades.

• Frame stripped, sandblasted, and refinished in correct Husqvarna silver
• Complete nut-and-bolt rebuild with re-zinc-plated hardware
• Engine fully rebuilt from the crank up

The goal appears to have been clear: preserve the soul of the 1975 World Championship machine while elevating reliability and performance.

Suspension & Chassis

Modern touches include:

• Brand-new Öhlins rear shocks
• Fully rebuilt forks with new chrome uppers
• VintageHusky.com billet triple clamps
• Takasago Excel rims laced with Buchanan spokes
• Michelin Starcross tires

The addition of Öhlins suspension alone significantly modernizes the ride quality without compromising vintage aesthetics.

Engine & Drivetrain

The engine has reportedly seen only three heat cycles and approximately five minutes of ride time since rebuild. Work includes:

• Re-bored cylinder
• New piston and rings
• New crank bearings and seals
• Transmission serviced
• New clutch components
• New ignition coil and wiring
• New chain and sprockets

In short, this isn’t a cosmetic restoration hiding tired internals — it’s mechanically renewed from the crank up.

Period Style, Modern Rideability

Additional upgrades include:

• Tag aluminum handlebars
• Works Connection quick-adjust perches
• IMS Pro Series stainless footpegs
• Restored tank with decals under clear
• Rebuilt seat with new foam and cover

The listing also notes inclusion of a World Championship wreath airbox logo — a fitting nod to the Mikkola era for this high-spec build.

The 400 CR: The Last of a Breed…

The 400 CR represents the final years before the monoshock revolution would change motocross forever. It is a machine from the height of the twin-shock era — raw, mechanical, brutally honest. It’s also part of a lineage that includes names like Tony DiStefano, Gary Semics, Bengt Aberg, and countless privateers who lined up behind the Swedish red tank.

For collectors, the 1975 model year stands as a high-water mark — the year Husqvarna ruled the world. For riders, it remains what it always was: a lightweight, torque-rich open-class weapon forged from Swedish steel. And for anyone who grew up watching On Any Sunday, it’s more than a motocross bike. It’s a legend.
