BGB! I have a late 80s model Kawasaki KH-125 2 stroke and it looks identical to yours.
im a skinny guy, 6' and 11.5 stone and it goes like poo off a shovel i tell thee.....
its off the road now though because of (lmao ASTAC) oil injection failiure.
you know when you are on a long clear road and you lie forward on the tank and put your legs up on the pillion and go 95MPH on a 125.........no?.......maybe its just me....anyhow, was doing that and oil broke engine seized and back wheel locked. would you belive i didnt even fall off
at around 80mph!
skidded for a few hundred meters then hit the gravel trap at the side.
never been so scared.
on top of that the head gasget blew at the same time so now the engine is in need of a re-bore.
i love bikes.
PS: ASTAC: is that a 20mm cannon on the front of yours?
