I purchased the KB-100 in 1994.Its now 8 years and 58, 000kms & the bike still performs as if its new.
The secret could also be that apart from two occasions in the last eight years I have never shared this bike with anyone else.
There are a few problems like the slow First gear & the sound.But all in all this bike can really take an Impact without injurying the Rider.
The Clogging of the Tank filter in due course of time does occur.
But this bike has good pickup & has lived upto its name of being a Good Maintence free bike all in all.
