Back in 1980 ADB was giving away a pair of these pantalooms described as... Tycons own padded denim pants with protection in all the vital impact points, feature a stripe up the legs, and are easy to maintain if you have access to a washing machine.
After seeing what I did with Dads lawnmower trying to swap the 160cc motor into my 125cc minibike there was no way my Mother would let me access her washing machine...
and maybe Honda and Yamaha riders wouldn't buy blue pants with a yellow stripe back in the day? Who knows why Tycon pants didn't take off
they advertised heaps back then.
