Hi The bars are about 12 inches high. And as far as I can remember the only cables I had to extend was the brake cable and these can be picked up anywhere. the original bars on these are really wide so instead of going out your just going up with the throttle and clutch cable..
Hi both came from eBay. The rear fender is actually for a trailer. The seat is also from eBay. It is solid plastic but I made a steel base and welded fixings for springs and then to bolt to bike. I also them covered the seat with foam and the leather look material which was a car seat cover.
