85cc, kids motorbikes

For the aspiring racers

KTM 85 SX 17/14 is sure to give your 7 to 10-year-olds a hands-on feel of the world of motocross fun. It can be a great way to kindle their interest in motocross racing and even aspire to become a pro if they wish. Of course, this also gives the flexibility to go on long dirt bike trails for some family fun. 

At the first look, you will notice a striking similarity with the big KTM bike range, and for a good reason too. It is designed to be inspiring for kids to take motocross, both for fun now and professionally later on by emulating their favourite bike riders and heroes.

At the same time, this kids motorbike bike comes with a host of safety features like a new transmission drive shaft to enhance safety. In addition, the muffler has been adapted with wool packaging to bring down the overall weight and to make it more suitable for young kids.
