Suzuki Sp370
The Suzuki Sp370 has a top speed of ~145 km/h (estimated), produces ~27 hp and weighs ~122 kg. Motoryk rates it 6.5/10.
The Suzuki SP370 was introduced in 1978 as a dual-sport/enduro motorcycle, building on Suzuki's successful SP series that began with the SP370 replacing the earlier TS and RV models. It was notable for being one of the more capable street-legal enduro bikes of its era, offering a balance of on-road compliance and off-road capability. The SP370 helped establish Suzuki's reputation in the dual-sport segment before eventually being succeeded by the DR series in the early 1980s.

What Buyers Should Know
Proven Thumper Engine
The SP370 uses a simple, air-cooled single-cylinder 370cc four-stroke engine known for durability and easy DIY maintenance. Parts are straightforward to source for a bike of its era.
Watch the Electrics
Being a late-1970s bike, aging wiring harnesses and corroded connectors are the most common issues found on surviving examples. Always inspect the electrical system thoroughly before buying.
Modest Collector Value
The SP370 holds modest but stable value as a vintage dual-sport, appealing to classic off-road enthusiasts. Well-maintained examples tend to sell steadily rather than depreciate further.
Generations & Specs by Year
Initial release; 370cc single-cylinder four-stroke, dual-sport enduro, replacing the SP370 predecessor SP370 debut model.
"Honest dirt-to-tarmac tool that doesn't pretend otherwise."
The SP370 is what happens when Suzuki stops compromising and just builds a proper dual-sport — the 370cc thumper pulls cleanly from low revs and that extra displacement over the old SP250 makes a real difference on rocky fireroad climbs where you need torque, not revs. On the road it'll sit at 110 km/h without complaint, though past 120 the vibration through the bars reminds you what this thing actually is. The seat is tall enough to be awkward for shorter riders on technical singletrack, and the stock suspension is soft in a way that feels generous until you hit a sharp square-edged rock at speed. Maintenance is dead simple — this SOHC single is about as mechanically transparent as engines get, and parts availability in '78 was genuinely good.

Used Buyer Review
"A tough, honest thumper that rewards patient, mechanically savvy buyers."
$1,200-$2,800 usedThe SP370 is one of those bikes that does exactly what it promises and nothing more. Suzuki built this thing like a tractor — the thumper engine takes abuse, starts cold without drama, and the simple frame geometry means any half-decent mechanic can sort it out. If you find one that's been maintained, it'll probably outlast you. The dual-sport setup works surprisingly well for fire roads and light trail riding, though don't kid yourself thinking it'll keep up with a proper enduro machine in serious terrain. The weak points are real though. Parts availability is genuinely painful — this isn't a GS500 where you're tripping over spares. Carb work is almost guaranteed on any used example, so budget for a rebuild. The suspension is agricultural at best, and anyone over 200 pounds will bottom it out on anything rougher than a gravel driveway. Check the frame around the headstock carefully, because these got worked hard by owners who thought they were buying a dirt bike.
