KEMIMOTO 30 Series Go-Kart Drive Belt 3-Pack — 30 Series Torque Converter, 5–7 HP, Aramid Reinforced

KEMIMOTO's 30 Series 3-pack drive belts are reinforced torque-converter belts designed as direct replacements for Comet 203589 and Manco 5959, delivering rugged, heat-resistant power for 5–7 HP go-kart engines.

When you need a reliable replacement belt built for off-road use and high-RPM conditions, this three-belt set from KEMIMOTO offers a heavy-duty construction and proven compatibility with a wide range of small-engine torque converters. Each belt uses a five-layer build with aramid reinforcement and dual nylon tooth coatings to resist stretching, wear, and thermal breakdown so you spend more time riding and less time maintaining.

How is the KEMIMOTO 30 Series belt constructed for durability?

The belt uses a five-layer architecture combining woven aramid fibers, double-thick neoprene rubber, and nylon-coated teeth. This layered approach balances flexibility with tensile strength to resist delamination and tooth wear under load.

• Woven aramid core for high tensile strength and reduced elongation
• Double-thick neoprene for shock absorption and shape retention
• Dual nylon tooth coatings to reduce friction and tooth shear
• Elastomer-impregnated tooth fabric for consistent engagement with pulleys

What temperatures and conditions can these belts handle?

Designed for extreme trail and track environments, the belt resists performance loss across a wide temperature range to limit cold cracking and heat-related degradation. That makes it suitable for off-road, variable-weather use where belts often fail early.

• Operates effectively from extreme cold to high heat environments
• Improved heat dissipation reduces glazing and premature wear
• Neoprene and aramid layers maintain flexibility in low temperatures

Which engines and models is this belt compatible with?

This 30 Series belt is sized and shaped to fit many popular go-kart torque converters and small-engine applications. It is intended as a direct or near-direct replacement for several common OEM part numbers and kart models.

• Direct replacement for Comet 203589 and Manco 5959 part numbers
• Compatible with Coleman KT196, CK196, GK200 and similar 196cc engines
• Fits many Manco, American Sportworks, Ken-Bar, Dingo and TrailMaster karts
• Recommended for 5 HP–7 HP torque converter setups

What are the sizing and performance specifics to expect?

The belt’s cross-section and tooth profile are engineered to retain shape under load and spread force evenly across the pulley face to reduce speed variations. This helps maintain smoother acceleration and longer service life compared with thinner, single-layer belts.

• Width: 0.74 inch (enhanced) for improved contact area
• Thickness: 0.39 inch to preserve tooth geometry and flex
• Precision tooth profile ensures even force distribution and reduced slippage
• Three belts included for spares or multiple karts

Who is this for? The KEMIMOTO 30 Series 3-pack is aimed at off-road enthusiasts, rental shops, and weekend racers who need dependable replacement belts that tolerate harsh conditions and keep torque converters performing consistently. If you maintain small-engine go-karts, ATVs, or utility vehicles with 5–7 HP engines and use Comet or Manco-style torque converters, these belts are a practical, value-minded upgrade for longer life and steadier power delivery.
