Why Standard Tubes Just Don’t Cut It

Riding electric motocross or enduro bikes through rough terrain often leads to one frustrating issue — flat tyres. Pinch flats, rock strikes, and sidewall tears can ruin your day, cost you races, or leave you stranded.

Why the Kenda Super Tuff Changes Everything

The Kenda Super Tuff Inner Tube 70/100‑19 is engineered to eliminate those worries. With its ultra-heavy-duty 3.7 mm butyl rubber construction, it offers top-tier puncture resistance for electric and off-road bikes. It’s one of the toughest tubes you can put between your rim and the dirt.

How to Ride Stronger with Kenda Super Tuff

1. Check your tyre size (70/100‑19 or 2.50‑19)

2. Replace your standard tube with the Kenda Super Tuff

3. Ride with confidence on motocross tracks, rocky trails, or enduro stages — without the fear of flats

The Cost of Doing Nothing

Without proper protection, you risk blowing out a tube mid-race, walking your bike off the trail, or constantly repairing punctures. Standard tubes simply aren’t built for the punishment serious riders dish out.

The Confidence to Push Every Ride Further

With Kenda Super Tuff, you ride harder, longer, and with less worry. You stay focused on your line — not your tyre pressure. Whether it's a Sur-Ron Ultra Bee, Talaria, or your youth MX bike, this tube helps your bike stay rolling no matter the terrain.

✅ Whether you're riding on the road or off-road, using a low-quality inner tube can put your safety at serious risk. Here’s why you must choose a high-quality inner tube for your bike:

🚨 Puncture Protection: Inferior inner tubes are more prone to punctures from sharp debris, glass, or rocks, increasing the risk of sudden flats and dangerous blowouts.

🚨 Air Retention & Stability: Poor-quality tubes lose air quickly, leading to unpredictable handling and increasing the chance of loss of control, especially at high speeds.

🚨 Durability & Reliability: Weak tubes can fail unexpectedly, leaving you stranded or causing an accident in high-traffic areas or rough terrain.

🚨 Performance & Grip: Low-grade tubes can affect tire pressure, reducing grip and making braking and cornering less effective, particularly on wet or uneven surfaces.

🚨 Rolling Resistance & Efficiency: A bad tube can slow you down and force you to exert more effort, leading to fatigue that could compromise your awareness and reaction time.

⚠️ PROTECT YOURSELF – CHOOSE A HIGH-QUALITY INNER TUBE

A reliable inner tube reduces the risk of accidents and ensures a smoother, safer ride. Always inspect your tubes, choose the right type for your riding conditions, and replace them regularly to avoid unexpected failures.

❓ Frequently Asked Questions (FAQ)

Q1: What tyre sizes is this tube compatible with?
✅ This tube is designed for 70/100‑19 and 2.50‑19 tyres. It may also fit some custom or lightweight applications with the same diameter and width. Always check your tyre sidewall for exact sizing.

Q2: Can I use this tube on the rear wheel?
⚠️ While it is primarily used in 70/100‑19 front tyres, it can be used on a rear wheel only if the tyre is exactly 70/100‑19 or 2.50‑19 and the rim is narrow enough to accommodate it.

Q3: How thick is this tube compared to standard and heavy-duty tubes?
🛡️ The Kenda Super Tuff has an ultra-thick 3.6–3.7 mm wall, making it thicker than both standard (~1.2 mm) and heavy-duty (~2.5 mm) tubes. It offers maximum puncture resistance in aggressive off-road conditions.

Q4: What type of valve does this tube have?
🔩 It uses a straight metal Schrader valve (TR-4 spec), compatible with most off-road and motocross rims.

Q5: Is it difficult to install because of the thickness?
🔧 Yes, due to its extreme thickness, installation requires extra care and strength. Slightly inflating the tube before fitting and using proper tyre levers and lubricant can help prevent pinching.

Q6: Is this tube suitable for electric bikes like Sur-Ron or Talaria?
✅ Yes! This tube is a popular upgrade for Sur-Ron Ultra Bee and Talaria Sting MX3/MX4, especially for riders encountering rocky terrain or frequent flats.

Q7: Does it work with tubeless tyres or rims?
⚠️ Only if your tubeless rim is tube-compatible (i.e., has no sharp edges or spoke holes that could damage the tube). It is not recommended for true tubeless-only rims.

Q8: Why is it more expensive than regular tubes?
💰 The Super Tuff tube uses premium-grade butyl rubber and is engineered for maximum durability and puncture protection, making it a long-term investment for serious off-road riders.
