Got one on my CR. It's a nice item, but I would be reluctant to spend 10% of the value of a bike on a pipe guard. That money is better spent on other items like a steering damper or suspension work. Or save the $ to go toward a newer bike someday.
I was going to put one on my KX, but I crashed before I had a chance. I hit so hard that the pipe was twisted/kinked at the inlet (near the engine). The pipe guard wouldn't have helped in my case - it would have made the kinking worse (even less power) and I would have been out the cost of both the guard and the pipe. :eek:
It think it would have helped in the case of "normal" dents, but the guard is pretty pricey. I'm still on the fence regarding this issue........ :confused:
True. You can get a lot of protective armor for what a new bike costs. But you can also spend too much trying to make a $1,000, 15 year old bike as good as a $3,000 two or three year old bike.
IMO, improved suspension and steering dampers are also protective equipment, for your bike and your body. Less crashing = less repairs + more fun.
For $150+- he can get Race Tech cartridge fork emulators for his '89 KDX. From personal experience (I had a '90 and my buddy had an '89) I can tell you that this is money very well spent. Improving the forks makes a HUGE difference on an older KDX. Or if he puts the money toward a steering damper, he can transfer that to a new bike someday.
Also, on the KDX, the stock chain guide is a weak link and can easily be bent by rocks or roots, locking up the wheel. I have seen this happen on 3 occassions, and once is was a major hassle. For the cost of an eline guard, you can get a regular pipe guard and and FRP chain guide for the KDX.
