02 · PRODUCT RANGE

Select by Rider Level, Chassis and Performance Target

For motocross and enduro products, displacement alone is not enough to define the right motorcycle.Wheel size, rider fit, power delivery, motorcycle weight and suspension capability determine where a model belongs in the lineup. KAMAX therefore offers different chassis and powertrain levels for distributors building youth, training, full-size and performance-oriented off-road programs.

03· Product Comparison

Build the Right Product Mix

A strong motocross range should give each platform a clear rider and commercial role.
Compare the five featured models by rider level, standard engine, chassis format and the reason each platform belongs in the lineup.

Model	Positioning	Engine	Chassis	Best For	Key Advantage
K65	Youth Progression	140cc X150 · 4-Stroke · 4-Speed	17″ / 14″ · 760 mm Seat	Youth training · Manual-clutch skill development · Recreational off-road	Compact chassis introduces manual clutch and geared motorcycle control before riders move to full-size MX geometry

04 · Market Fit

Different Platforms for Different Market Needs

Motocross products should progress with the rider. A commercially clear range normally moves from appropriately sized training motorcycles into full-size platforms, then separates configurable volume products from higher-standard and performance-oriented models.

YOUTH PROGRESSION

Develop Manual-Clutch and Gear-Control Skills. Youth riders progressing beyond simpler beginner motorcycles need a chassis that remains manageable while introducing conventional motorcycle controls.

Recommended： K65

FULL-SIZE PROGRESSION

Move into Full-Size Geometry. Once the rider has developed basic off-road control, chassis size becomes the next major step. Transition from compact youth platforms into full-size off-road riding.

Recommended：K85 4-Stroke

CONFIGURABLE FULL-SIZE MX / ENDURO

Cover Multiple Price and Performance Levels from One Platform. For distributors serving several customer levels, carrying a completely different chassis for every engine specification can increase product, parts and service complexity.

Recommended：K20 . K23 NC300S

LIGHTWEIGHT 300CC-CLASS MX / ENDURO

Start from a Higher Standard Baseline
Some markets do not need a basic 250cc starting point. They require stronger standard power, six-speed transmission and a lighter full-size package from the beginning.

Recommended: K16

05 · OEM / ODM & Supply

Built Around Your Market Requirements

On an MX / Enduro motorcycle, engine, chassis and suspension decisions are connected.

A more powerful engine may require different cooling, fuel-system, protection or chassis specifications. Likewise, suspension and rider-control upgrades should reflect the intended rider and retail level rather than simply increase the option count.

KAMAX supports distributors and private-label partners with project-level configuration based on the selected platform.

K65 is the clearest compact youth-progression model among the five featured motorcycles.
It uses a 140cc four-stroke engine, manual clutch, four-speed transmission, 17″ / 14″ wheels and a 760 mm seat height. It is designed for riders developing conventional clutch and gear-control skills before moving to a larger chassis.

No.
K85 4-Stroke uses full-size 21″ / 18″ wheels, a 920 mm seat height, adjustable suspension and a 285.8cc six-speed four-stroke engine.
It is better positioned for experienced youth riders progressing into full-size geometry than for riders requiring a basic first motorcycle.

K65 is a compact youth training platform; K85 4-Stroke is a much larger full-size progression platform.
K65 uses 17″ / 14″ wheels and a 140cc engine.
K85 4-Stroke moves to 21″ / 18″ wheels and a significantly stronger 285.8cc powertrain with adjustable suspension.
They serve different stages of rider development.

K20 is the most configurable full-size platform among the featured models.
The standard specification uses a 249.9cc CB250-F, but the platform supports multiple alternative 250cc, 300cc and higher-output engine directions.
This allows distributors to develop several price and performance levels without introducing a completely different chassis for every engine specification.

K20 prioritizes configuration flexibility; K16 starts from a higher standard performance level.
K20 uses a 249.9cc air-cooled CB250-F in its reference specification.
K16 starts with a 279.6cc water-cooled NB300, six-speed transmission and a published 105 kg net weight.
Choose K20 when multiple specification levels are required around one platform.
Choose K16 when the product needs to begin from a stronger 300cc-class standard package.

K16 emphasizes a lighter 300cc-class standard package, while K23 NC300S carries the stronger performance position.

K16 uses the 279.6cc NB300 and has a published net weight of 105 kg.

K23 NC300S uses a 283cc engine producing 25 kW and combines it with a chromoly frame and fully adjustable suspension.

For distributors, K16 and K23 should therefore occupy different price and performance roles rather than compete as two similar 300cc models.

K23 NC300S has the strongest published standard engine output among these five featured models.

Its reference NC300S configuration produces 25 kW at 9,000 rpm and 27 N·m at 7,000 rpm.

Alternative engines are also available for project-specific K23 configurations.
