    I installed the Silicon hoses about 2 years ago. I also installed a new thermostat and upgraded fan switch this year. I did notice a bit of difference with just the hoses, but that was probably due to not leaking coolant anymore. I noticed more of a difference with the upgraded fan switch/new thermostat. I think that you will see more of an improvement in heat management if the hoses were intstalled with the fan switch as opposed to hoping for a noticeable difference with just the hoses. I ended up getting the Motion Pro crimpers.

    A lot of talk about leaking hoses, and these hoses are supposed to be trick?

    I'm not seeing it, I guess. :huh

    Take the "not" out and it makes sense.

    It's called heat soak. Basically what is happening is that the heat is transferred from the engine to the radiator fluid, then goes to the radiator to be cooled. Well, the stock rubber hoses don't keep the heat in the hoses but lets it seep out into the engine compartment. So now you're running an engine in an oven, essentially. Because of this the radiator has to work even harder to cool the engine.

    Put on the thicker Samco hoses and no heat is allowed to seep through the hoses into the engine compartment; the only place the heat is allowed to dissipate is at the radiator. Since the engine is now not-in-an-oven, it runs cooler, simply because there's not so much damn heat in the compartment. This lets the radiator run more efficiently and actually cool the engine, not the entire engine compartment.

    Think of it like this: it's 95* outside and you have every window and door in the house open. A/C is going nuts, right? Can't cool the house no matter how hard you run the A/C unit. Close the doors and windows (I.e., change the hoses) and now you have better insulated the house (engine). So now when the A/C unit (radiator) cools the house, it actually works.

    I had similar problems. Used a radiator pressure tester to find any leaks.

    The hoses don't leak, it's the connections that do. Mostly I feel because the clamps are the issue; not knowing how tight is tight, not having the correct clamp tool and lastly, some of the hoses need trimming which causes the joins to be under bending loads.

    If I remember right, the instructions don't address any of these things.

    That would make sense to me if the radiator wasn't exhausting its added heat onto the engine and into the area those hoses ostensibly are isolating their heat from.

    Whatever-- they look kind of cool.

    FYI .... KTM's come stock with the silicone hose clamps....so no need to purchase them unless they get damaged.

    www.MotoHose.com sells the clamps for $1.95 :clap cheaper that what KTM sells them for.

    I put on Samco hoses this year. I like them so far. It took some cutting on two of the hoses to make them fit.

    Just a heads up: Samco will not warranty their hose kits unless you buy their clamp kit when you buy the hoses.

    In other words. We had offered a stepless hose clamp kit a while ago and it fit nicely both with installation and with durability. Unfortunately for some reason Samco then announced their hose kits would no longer be warrantied if you didn't use their hose clamp kit. The downfall with their hose kits unlike their top of the line hoses is the clamps are from the automotive side of things and not for motorcycles. This causes certain frustrations with installation because of size limitations and we all know that just like the auto world, motorcycles aren't getting any easier to work on but harder with every new year. They're simply isn't much space to get in there and mount an over-sized automotive hose clamp. We haven't had a single Samco Hose fail in all the years that we have been selling their line of products which shows their build quality with their hoses. KTM is using Samco on all their race efforts. That should tell you something. It's up to you on whether you choose to use their clamp kit that comes with the hoses or purchase the OEM Stepless units from the microfiche section. I hope that helps and clears up some things about Samco.
