Work great on my sons ktm50. Meant for a bigger bike, but I trimmed them down and they're perfect.

Installed these on two KX100's for my sons and left for three days of riding. At the end of day one, had to remove them from both bikes. Fortunately we were able to replace them with a stronger product from a local shop. Not putting down Acerbis or their product here but the rating depends on what you're looking for. Facts from my experience.

If you are looking for something to "shield" your child's hands from wind/weather or very small limbs while cruising (no drops or collisions) - they'll serve the purpose. Rating - 3.

If you are looking for something to truly "guard" levers and fingers - continue your search. Rating - 1

With that, if they fit your need, mounting was very simple and easy.

I don't understand the reviews saying these are flimsy. They're for a kids' bike - how much force will they truly be subjected to? We all want the best for our kids but I seriously doubt your kid is going to break these in the course of normal riding and crashing. They're very sturdy and mounted up in minutes with the included mounts and hardware, with no slippage on the bars as some others had experienced. I had a set of the "adult" version a few years ago and thoroughly crash tested them over several seasons, so I had no reservations about buying these for our mini. Being plastic/nylon/whatever with no metal "spine" like other models have there is a very small amount of flex, but it's more like shock absorption than weakness. They are far more than "brush guards". Their purpose is to prevent little fingers from getting pinched and smashed and they excel at that. Stay grounded, my friends.

Easy to mount on my sons XR70R. They seem to protect his hands fairly well from brush but not as well as larger guards that are made for adult bikes. Still much better than nothing.

I am very disappointed in this product. The clamps used at the inside (near handlebar center), are now made of plastic. They did not always be this way because I have an older pair from a couple of years ago that were on another kids bike and they are metal. Plastic is cheap easy to break and so are these guards now.

Not a very good product, the bolts that go in the end of the bars don't hold the gaurds very good and the pieces that clamp to the bars are plastic.

All the mounting hardware is now plastic which back in the day it was metal. There's a little flex to it now because of that

is all in plastic to fragil

I have been looking for hand guards for my sons KTM SX 50. I cold not find any made for mini bikes. Although in the description it says for 70cc or larger, I took a gamble and they bolted right on to his 50's Pro Taper bars without out an inch to spare. Look great. Note these are more hand guards than bark buster with out a metal bar running the entire length but at the slower speeds through the woods should be better than nothing.
