RIM LOCK - HOW DOES IT WORK?

Have you ever wondered how does a rim lock work and how to choose the correct rim lock for your motorcycle? Then this video is for you.
A motorcycle rim lock is a device used to prevent the tire from spinning on the rim, particularly in off-road or high-torque situations. It consists of a metal clamp that attaches to the wheel rim and holds the tire bead securely against the rim flange. This prevents the tire from slipping or rotating on the rim under heavy acceleration or braking, which could cause damage or loss of control. The rim lock is typically installed opposite the valve stem on the rim, and it's tightened securely with bolts or nuts to ensure it stays in place.

If you carry tools while travelling 👉 www.roiamoto.com/toolroll Thanks for checking it out! Would love to hear your feedback!

Thank you for actually measuring the rims

[@katabatic66]

I understood the camshaft, but couldn't understand the rim lock. Perfectly explained, thank you man ¡¡

[@RoiaMoto]

Glad to hear!! 😎

Wikipedia for crf300l/Rally is Roia Moto "Academy?" Yes it is as it should be. More about the Rally, much appreciated.👍🍻

The best video representation of rim lock! Subscribed!

Cheers, mate! Welcome to the channel

[@redpepper007]

yeah, I got mine installed without the counterweight and now its so funny to drive. Will balance it on my own.

[@RoiaMoto]

I needed to add quite a lot of wheel weights for the rear wheel. Don’t be surprised when you are doing. I’ve added about 80 grams to it.

[@redpepper007]

@@RoiaMoto I added 180 grams and now its driveable lol. Will get to local dirtbike service and have them balance both wheels normally because I did the garage method - large metal piece strapped to spoke with zipties 😅

[@StreakyP]

silly question... tyres often have a balance dot on them for the lightest point & normally you put this at the valve to compensate for the valve weight & minimise additional balance weights. Given the rimlock is now going to be the biggest imbalance should you put the tyre balance dot at it instead? (rather than at the valve).

[@RoiaMoto]

Hi mate! Not silly at all! It’s a perfect valid point! Before installing Rim locks the heaviest point of my front wheel with tyres was exactly at the valve stem. After installing rim locks, the heaviest point shifted to a point between the rim lock and valve stem. I can conclude that the rim lock helped to offset some of the weight of the valve stem. Unfortunately it’s impossible to precisely know in advance where the heaviest point will be for every tyre, wheel, tube and rim lock combination but your point makes total sense. On my next tyre change I'll line up the dot on the tyre to the Rim lock and see how it goes. thanks for your comment!

Excellent video. Finally, after years I finally understand it. Thanks!

[@RoiaMoto]

Thanks for the supportive comment!! Fantastic to hear that! Lots of people talk about rim lock but that’s should make it clear how it actually prevents the tyre spinning on the rim. Cheers

@@RoiaMoto It sure is. And you are good at it. Great job!

Hi Italo, another great information video explaining how a rim lock works! I particularly liked your use of a digital vernier calliper to show the internal rim widths which will be extremely useful for anyone considering buying Motion Pro Liteloc rim locks for their CRF300L. Please keep these excellent videos coming! Cheers!

[@RoiaMoto]

Thanks for the comment, Adrian!! As always very supportive to hear that the video was useful! Many more videos coming

[@ivanbrambarov3022]

Great video as always! I don't know how useful this rimlock is though... do you think that this type of tire "slippage" is really a big concern for non-performance everyday bikes? And it looks like more of a trouble if you need to change a tire somewhere in the wild. Also, at first I thought it uses the opening for the valve stem, but later you showed that it is on the opposite side of the rim - does that mean that you have to drill a new hole in the rim? That doesn't sound very good to me.

[@RoiaMoto]

Hi Ivan and thanks for the comment! For the CRF300L it’s very unlikely that the tyre would slip on the wheel due to power/acceleration . The main advantage I see is that even in case you get a puncture/flat the rim lock should allow you to “limp” back at slow speed to a place where you can fix the issue. Regarding the hole, the CRF300L wheel already comes with a hole for the rim lock.

Nice explanation video... please make a video of the bolt torque measurement on the crf300l. I think this is very useful. Thx 👍

[@RoiaMoto]

Thanks, Boris! You mean a video showing all torque specs of the CRF?

[@alexanderwright9064]

Great practical demonstration. Question: Are you using the heavy-duty tube in front tyre. I am changing my front, irc tyre. Fitting the motion pro rimlock also on front . Did the rear last week..using standard tube and motion pro rimlock. Also, if throwing away old tyre wouldn't it be easy just cut off old tyre. I'm getting mine done at the garage. But have tools and jack I saw on earlier vid of yours.So if do a trail flat tyre your vid is helpful! Keep them coming, mate!

[@RoiaMoto]

Thanks as always for the comment, Alex! Yes, I have the heavy duty tube only on the front. I’m already working on a video to change the tyres with manual tools that people usually carry on trips / trails.

[@alexanderwright9064]

Thanks, mate. I will put the heavy duty on the front tyre and a rimlock. I took your advice on the standard tube on the rear and added rimlock. .looking forward to your next video.

[@osal4323]

what do you think about Tubliss?

[@RoiaMoto]

Hi Osal I never used but from what I couldn’t gather. I should be considered for 100%. I always need to ride some tarmac… Not sure it’s that right choice for me

[@arpittiwari5735]

Can i use it in Himalayan 411 2022 model?

[@RoiaMoto]

Rim locks can be used with any tubed tire.
