HOLATO Inner Tube Kit 90/100-14 & 70/100-17 — 2-Pack TR4 Valve Stems with Valve Cores & 4-Way Tool

These are replacement inner tubes (rear 90/100-14 & front 70/100-17) with TR4 straight valve stems, supplied as a 2-pack plus valve caps, spare cores and a 4-way valve tool for 110–160cc pit and motocross bikes.

If you need durable, correctly sized inner tubes for small-displacement dirt, pit or trail bikes, this HOLATO kit offers two heavy-duty rubber tubes with TR4 straight valve stems and a basic tool kit to help you fit and maintain them. The set covers common 14- and 17-inch wheel applications on many 110–160cc machines and a broad range of small motocross models.

Which bikes and tire sizes will these inner tubes fit?

This kit includes one 90/100-14 (3.00-14) tube for 14-inch rear wheels and one 70/100-17 (2.50/2.75-17) tube for 17-inch front wheels, with TR4 straight valve stems. It's compatible with many pit and mini motocross models from brands like TaoTao, Apollo, Coolster and common OE models for KLX, KX, TTR, YZ, CRF and similar small-displacement bikes.

• Rear tube: 90/100-14 (3.00-14) — fits 14" tires
• Front tube: 70/100-17 (2.50/2.75-17) — fits 17" tires
• Compatible with 110cc–160cc pit and dirt bikes and many small motocross models
• TR4 straight valve stem for standard valve access

What hardware and extras come with the tubes?

The package contains two inner tubes and practical accessories so you can install and service them without immediately needing extra parts. The included valve caps and spare cores help maintain air retention and let you replace worn parts in the field.

• 2 x inner tubes (one 14" size, one 17" size)
• 2 x red valve caps and 2 x black valve caps for identification or spares
• 2 x spare valve cores for quick on-trail repairs
• 1 x 4-way valve tool for removing/installing cores and basic tire work

How strong and reliable are these inner tubes?

HOLATO inner tubes are produced from high-grade rubber designed to resist abrasion and hold air under typical off-road and trail riding conditions. They are waterproof and wear-resistant but, like all inner tubes, still require correct mounting and tire condition checks to perform reliably.

• Constructed from durable, wear-resistant rubber compound
• Waterproof material suitable for off-road environments
• Recommended to inspect tires and rim edges before installation
• Keep a spare core and tool handy for roadside repairs

How should I confirm fit before ordering?

Measure your current inner tube size and valve type prior to purchase. Compare the printed size on your existing tube or the tire sidewall to ensure the 90/100-14 and 70/100-17 dimensions match your wheels, and confirm you use a straight TR4 valve stem.

• Check the tube or tire sidewall for size markings
• Confirm your valve stem style is TR4 straight valve
• Review vehicle model fitment list if unsure (many 110–160cc models included)
• Contact seller with model/year and tire measurements if needed

Who is this for: Riders, mechanics and hobbyists who own small-displacement dirt bikes, pit bikes or junior motocross machines and need a ready-to-fit replacement inner tube pair with basic maintenance accessories. This kit is ideal for weekend trail riders, pit crews, and anyone who wants spares that match common 14- and 17-inch setups on 110–160cc bikes.
