DIY Offroad emergency rescue kit

Hey, great video! I have a few suggestions for your setup. If I understand correctly, the 32 kN pulleys are awesome, but for a 200 kg motorcycle, you could use much smaller pulleys. With a double block system, each pulley would only need to handle around 1 kN, so pulleys with a 6-8 kN rating would be more than sufficient. For the rope, I recommend using Dyneema rope with a 6 mm diameter and a strength of 3100 daN. This provides a tensile strength of about 3100 kg, which is more than enough for recovering a 200 kg motorcycle. Dyneema ropes are widely used in yachting because of their high strength, low stretch, and excellent resistance to elements like water and UV radiation. Plus, they save a lot of space and weight compared to traditional ropes, making them ideal for carrying on a motorcycle. As for the pulleys, ones with a 6-8 kN capacity would be lighter and still offer plenty of strength for this use case. While your 32 kN pulleys are top-notch, smaller ones would make the setup more compact without sacrificing safety. One more thing: I noticed you tied the rope around the front forks for recovery. I strongly advise against this. The front forks are only secured by the triple clamps and are not designed to handle significant lateral or pulling forces. Putting high loads on the forks could cause them to bend or come loose, especially under tough recovery conditions. Instead, I suggest tying the rope around the crash bars. These are bolted to the frame and are much better suited to handle the forces involved in recovery. Thanks for the video.

Hi petrki, thanks a lot for your Input!😊 Tomscholtes also recommended the dyneema rope and even offered me some for testing purposes. I will try it and make a follow up, and I’ll try to find budget friendly sources so that anyone can copy this kit as low cost as possible himself. 🎉I’ll also have a look for some smaller pulleys to upgrade the kit 😊

Get para cord! Dineema gathers grit an bits, these then work deeper into the rope an cut from the inside! An yes it snaps when you are upto your eyes in crap etc. I learnt this from the Aussie 4x4 challenge events. Dineema should stay where it was designed for! SHIPS! Best of luck.🙏🙏👍👍🇬🇧🇬🇧🏍️🏍️

Thanks for the advice, already had ppm (6mm paracord) in mind because it at least holds up to ~1000lbs but the big issue here is that it stretches up to 30% and that’s a pain in the guts when your pulling… trust me… I tried

Hi, very interesting content. Regarding the dyneema cord , I can assure you that the 6 mm hold up to 3500 kg before braking. Also they do not expand that much under tow like a standard dynamic climb rope. I have lots of experience with dyneema since I use these cords to tow up gliders in our club. There is also no need to make an expensive purchase. Go to a gliding club that use a winch for glider towing. They normally have 2 dyneema cables of more than 1 kilometer length. And now the part where it gets interesting ;-): The cables are normally changed after 2 seasons, so the clubs have hundreds of meters used dyneema cable left. For further info please feel free to send me a PM :-)

Thank you very much for that tip, how can i reach you?

I could definitely see this being useful if/when I get into off road adventure riding. For me, the extra investment into Dyneema line would be worth it; the strength rating of even 6mm dyneema should be more than adequate for this use case, which should make the whole kit significantly smaller, lighter, and easier to work with. I also have a background in the sailing world, so I'd be tempted to borrow some hardware from there, though it may work out cost prohibitive. At the very least, I'd look to see if I could (affordably) implement a cam-cleat set up to prevent roll back - while that prusig looks like it would work, that 5-10% increased effort via friction is potentially undoing all the gains you just made by taking the luggage off the bike, and may be the difference between a successful recovery and a whole bunch of swearing and frustration!

Wow, this is a incredible good input, thank you very much for sharing this 😀 I’m definitely going to look into this dyneema line
