8 Motorcycle Wheel Myths: Spoked vs Cast Alloy Wheels

Spokes are always stronger. Alloys are fragile. A broken spoke is no big deal. There are some very confident opinions about motorcycle wheels out there, and quite a few deserve a closer look.

I filmed this video in Australia after questions from viewers about spoked and cast alloy wheels. These are the eight myths I wanted to tackle, drawing on what I’ve learnt through adventure riding and racing.

Watch: eight myths about motorcycle wheels

1. Spoked wheels are always stronger

The distinction I’m getting at in the video is how a wheel responds to a load or impact. A cast wheel is a rigid structure; a spoked wheel’s construction can offer useful flexibility over rough terrain.

That doesn’t give every spoked wheel a blanket win for strength. The design, materials and intended use of the particular wheel matter. I’d think about what you’re asking it to cope with, rather than choosing purely on the word spokes.

2. Cast alloy wheels are fragile

A rigid wheel can be damaged by a severe impact, but that doesn’t mean a cast wheel is fragile in everyday use. There are plenty built for demanding road riding, touring and track use.

In the video I talk about why I prefer spokes for rough, impact-heavy terrain. Check the intended use of the actual bike and wheels, though: cast wheels aren’t automatically excluded from every off-road situation. For example, BMW specifies the cast wheels on its F 450 GS for road and off-road use.

3. Spoked wheels always need inner tubes

Traditional spoke arrangements can make an airtight rim more difficult because of where the spoke nipples meet it. That’s why many spoked wheels use tubes. But there are also purpose-designed tubeless spoked systems.

This has been possible for a long time: BMW’s HP2 Enduro street-wheel information described a tubeless cross-spoked rear wheel back in 2006. The useful question is whether your exact wheel and tyre combination is approved for tubeless use.

Know which setup you have before packing puncture equipment. A tubed system and a tubeless system need different approaches, and the right response also depends on the damage. A plug kit won’t solve every puncture.

4. Cast alloy wheels are always lighter

Wheel weight depends on the specific design. A heavy-duty cast wheel can weigh more than a lightweight spoked alternative, so I wouldn’t make the decision from appearance alone.

In the video I mention visiting Talon Engineering and building a spoked wheel that I later raced in a desert rally. Seeing how a wheel goes together gives you a different appreciation of all the parts involved.

5. Spoked wheels need constant maintenance

Constant is the part I disagree with. Spoked wheels do need checks, because the spokes work together under tension to support the rim and hub. A loose spoke deserves attention.

I demonstrate a basic sound check in the video, but that isn’t a replacement for the inspection and servicing your manufacturer specifies. Getting spoke tension and wheel alignment right is a skill. If something sounds or feels wrong, have it checked rather than randomly tightening things.

6. You can’t ride fast on spoked wheels

My racing bikes use spoked wheels, so that one makes me smile. Spokes don’t automatically rule out higher-speed road riding or competition.

The wheel needs to be suitable for the job and in good condition, with the correct tyres, setup and balance. I’m talking about choosing appropriate equipment, rather than treating a wheel design as a speed rating.

7. Cast alloys are only for sports bikes

Touring, commuting and plenty of other road riding can all suit cast wheels. The right choice depends on the bike and the riding you want to do.

I’d look at the whole setup: terrain, tyre choice, approved wheel sizes, luggage and how you use the motorcycle. The style of bike on the showroom floor only tells part of the story.

8. A broken spoke is no big deal

This is the one I really don’t want people to dismiss. In the video I discuss the possibility of dealing with a broken spoke when you’re out riding, but that isn’t a promise that a damaged wheel is safe to ride home.

A broken spoke needs assessment and repair. Wheel condition, other loose or damaged spokes and any change in handling all matter. Follow your bike’s guidance and get professional help or recovery when needed.

Choose for your riding and look after what you have

My biggest takeaway is to get past the sweeping statements. Find out what your actual wheels are designed for, understand the tyre and tube setup, and give them the maintenance they need.
