Hyssk 2mm Heavy-Duty 18" Inner Tube — TR4 Valve, Fits 4.10/4.50-18 Tires (CRF230/250 Compatible)

Hyssk's heavy-duty 2mm inner tube is a reinforced 18" rubber tube with a TR4 straight valve designed to fit 4.10/4.50-18 and common 18" rear dirt-bike tires.

This premium inner tube was developed to balance durability, weight, and cost for off-road and pit-bike riders. Built from a thicker 2mm rubber compound and produced in ISO9001/DOT/E-Mark partner facilities, it aims to deliver longer service life than standard tubes while keeping rotational mass lower than bulky 3mm units. The tube fits a wide range of 18-inch rear tire sizes and many popular models including Honda CRF230/250 and Yamaha TTR250.

Which tire sizes and motorcycles will this tube fit?

The tube is sized for 4.10/4.50-18 sections and compatible with several common 18" rear tire designations such as 110/100-18, 110/90-18, 120/90-18, and 100/100-18. It also matches many dirt and trail bike models that use 18" rear wheels. Always confirm your tire sidewall size and rim compatibility before purchase.

• Common tire matches: 110/100-18, 110/90-18, 110/80-18, 120/90-18, 100/100-18
• Examples of compatible motorcycles: Honda CRF230/250, Suzuki DRZ250, Kawasaki KLX250, Yamaha TTR230/250
• Valve stem: TR4 straight valve for standard motorcycle rims

How does the 2mm thickness affect performance and durability?

The 2mm wall thickness is chosen to give a meaningful durability upgrade over thin stock tubes without the extra weight of a 3mm heavy tube. Riders get improved puncture resistance and longer wear while maintaining lighter rotational mass, which helps handling and acceleration on smaller dirt bikes. It’s a middle ground for riders who want tougher tubes without sacrificing control.

• Puncture resistance improved versus thin stock tubes
• Lighter than many 3mm heavy-duty options
• Better balance of strength and rideability for off-road use
• Manufactured in certified facilities for consistent quality

What quality standards and packaging updates should I expect?

Hyssk partners with factories holding ISO9001, DOT and E-Mark certifications, reflecting a higher level of production control and traceability than many generic suppliers. The brand is rolling out branded packaging and the thicker 2mm specification widely, improving recognition and making it easier to verify a genuine product. These steps aim to reduce variability and give buyers more predictable performance.

• Partner factories with ISO9001, DOT, E-Mark certifications
• Branded packaging rollout completed in Q1 2026
• Consistent 2mm wall thickness across updated stock
• Ongoing product refinement and quality control

How should I choose this tube over other options?

Choose this Hyssk tube if you want a durable, mid-weight inner tube that still keeps your bike lively. It’s aimed at riders who value longer service intervals and trustworthy manufacturing but don’t want the full added weight of extra-thick racing tubes. If you prioritize lowest price above all, a standard thin tube will be lighter on cost but not on longevity.

• Best for riders seeking a balance of durability and low rotational weight
• Good value compared with cheaper, thinner tubes
• Recommended when you want a reliable spare for trail or pit-bike use
• Not intended as a replacement for tubeless setups or specialty racing tubes

Who is this for: The Hyssk 2mm heavy-duty inner tube is aimed at dirt-bike, pit-bike, and trail riders who use 18" rear tires and want a dependable, longer-lasting tube with a standard TR4 valve. It suits owners of Honda CRF230/250, Suzuki DRZ/RM series, Kawasaki KDX/KLX, Yamaha TTR models and similar bikes who prefer a quality tube that reduces roadside failures without adding excessive weight. If you need certified production, clearer branding, and a practical balance of strength and ride feel, this tube is a fitting upgrade.
