Introduction To The SSR Bison 400

The SSR Bison 400 is a lightweight 391cc four-stroke dirt bike known for its low cost and decent capabilities as an entry-level trail and motocross machine.

SSR Motorsports is the importer that brings these Chinese-made bikes into North America and sells them at very affordable price points. This makes them appealing for beginners or intermediate riders not looking to spend a fortune.

The Bison 400 model first arrived for 2008 and continues today with minimal changes. It’s designed with new riders in mind thanks to the low 35 inch seat height, mellow powerband and electric start convenience.

In this SSR Bison 400 review, we’ll cover all of the key specs, features, performance abilities, reliability concerns, pros and cons, and who this bike best suits.

We’ll also compare the Bison 400 to some of the top alternative starter dirt bikes on the market.

SSR Bison 400 Engine And Transmission

The Bison 400 gets motivation from a 391cc air-cooled single cylinder four stroke engine, one of the largest you’ll find in the entry-level class.

Here are the key engine specs:

  • Engine: 391cc air-cooled single cylinder
  • Fuel System: Electronic Fuel Injected (EFI)
  • Starting: Electric start
  • Bore and Stroke: 68 mm x 55 mm
  • Compression Ratio: 9.2:1
  • Transmission: Automatic CVT, V-belt
  • Clutch: Wet multi-plate

This simple air-cooled thumper motor puts out a claimed 23 horsepower at 6,500 RPM, which is fairly decent from a 391cc starter dirt bike. The power feels linear and smooth, avoiding any major hit.

It’s paired to an Automatic CVT, V-belt transmission. Gear changes are smooth and clutch modulation is light.

Now let’s take a look at some other important specs including dimensions, weight and capacity numbers:

SSR Bison 400 Specs Chart

Engine391cc air-cooled single cylinder
Horsepower23 hp
Torque22 Nm
TransmissionAutomatic CVT, V-belt
Seat Height35 inches
Wheelbase55 inches
Wet Weight297 lbs
Fuel Capacity2.2 gallons
Top Speed65 mph

At just 297 pounds wet when fueled up, the Bison 400 is on the lighter side for a 391cc model. This helps handling feel relatively nimble despite the 55 inch wheelbase.

The 2.2 gallon fuel tank allows you to ride trails for 1.5 – 2 hours before needing to refuel. This is ample capacity for a starter bike focused on shorter rides.

SSR Bison 400 Key Features

The SSR Bison 400 is equipped with features designed to enhance the riding experience:

  • Electric Start: A convenient electric starter motor eliminates the need for kick starts. This is particularly beneficial for beginners, as starting the bike can often be a challenge.
  • Full Lighting: The bike comes with an electric headlight for night riding, as well as brake lights and signals. These features are not always included on cheaper dirt bikes.
  • DOT Tires: The Bison 400 comes with street-legal DOT-approved tires from the factory, allowing you to ride to and from trails without needing to change tires.
  • Disc Brakes: The bike features hydraulic disc brakes at the front and rear for more effective stopping power. Many competitors still use drum brakes.
  • Kill Switch: A safety kill switch on the handlebar allows you to quickly shut off the ignition in emergency situations.
  • Skid Plate: This feature helps protect the engine cases and underside of the bike from trail obstacles and crashes.
  • Steel Double Cradle Frame: This provides decent rigidity and strength, enabling the bike to handle jumps and rough terrain.

The inclusion of DOT tires, a headlight, and an electric start make the Bison 400 more street-legal and convenient straight from the dealer. You can take it home on the street without incurring additional delivery fees.

SSR Bison 400 Performance And Handling

The Bison 400 delivers a somewhat livelier performance compared to 250cc entry-level four strokes, thanks to its displacement advantage. While the power won’t blow you away, it offers enough grunt for trail riding and motocross.

The power delivery feels linear without much of a torquey hit, making throttle control easy for beginners learning how to manage power. There’s still enough torque down low for tackling technical trails and hills.

On straight sections and open dirt roads, you can wind the Bison 400 up into its mid-range. Realistically, you’ll cruise in the 40-50 mph range on trails.

The transmission shifts smoothly and the clutch has a light, predictable pull. Finding neutral takes some finesse but improves as you get used to it.

Thanks to its light weight of 297 pounds and shorter 55-inch wheelbase, handling is nimble enough. It’s easy to toss around on winding trails and remains stable at speed.

While the budget suspension components aren’t high-end, they still absorb bumps and ruts fairly well. You can push into corners aggressively and the Bison 400 tracks well on flat terrain and small hills.

When it comes to slowing things down, the front and rear hydraulic disc brakes offer ample stopping power for a beginner. They have good modulation without being too grabby or requiring a lot of finger effort.

Overall, the SSR Bison 400 offers a rideable mix of power, handling, and braking that makes mastering the basics enjoyable rather than intimidating.

Reliability Concerns

Reliability is hit or miss according to SSR Bison 400 owners. Some report problem-free operation while others experience issues like:

  • Electrical problems with the starter motor and lighting
  • Engine leaks from the head gasket
  • Carburetor problems
  • Faulty clutch components

Quality control and component tolerances are common complaints with Chinese motorcycles. Assembly and materials can be questionable at times.

The good news is that if properly maintained, many Bison 400s hold up just fine. It comes down to inspecting your particular bike closely and fixing any issues immediately.

Changing the oil regularly, checking bolts/fasteners, and replacing worn parts can go a long way toward reliability. Consider upgrading key components like the carburetor for even greater longevity.

Just don’t expect the same quality standards as the Japanese or European brands. There’s more risk buying Chinese but also more reward if you get a good example.
