Motorbikes are manufactured with the average rider in mind. This is fine as long as you are the size of the average rider, but it could become awkward if you are taller or smaller than the average rider. Riders who are not so tall, probably will recognize stopping on a hill or at the traffic lights "will I be able to put my feet on the ground, will I be able to keep the bike up?" A great feeling of discomfort and no trust in yourself or the bike. This is why Hyperpro produce height adjustment kits.
This kit will lower your motorcycle by 40mm.
