Have you tried a K0?
That will make you feel REAL short...those crazy side covers...the sandcast was slightly lower than the K0, though, as the original shocks were shorter by about 1/8". The 3/70-ish K1 got taller with the later. longer shocks.
Today, the metric tires are all taller than the old bias-ply (more oval cross-section) tires, too, by quite a bit! The K7's 17 inch rear makes that even more so.
In 1969-1970 Honda made us (shops) measure the customer's inseam and it had to be not less than 29" to sell them a 750. Honest! Talk about trying to do THAT with your average 60's rider...this responsibility was put onto the shop owners by Honda. We also had a "check list" that included making sure the buyer was not a brand-new rider (some were anyway), had at least 29" inseam, and was familiar with the traffic laws (don't know that we EVER asked that one, though).
My favorite instance: the banker who handled Spring Honda's bank accounts was 5'8" tall, probably had about 27" (if that) inseam, and weighed close to 200 lbs. He'd never owned, nor ridden, a motorcycle, but he HAD to have the 750 when he saw it. The first one in sold was to him. He couldn't ride it home: we trucked it to his house and garaged it. Every 2 weeks or so it would come in, parked in 2nd gear, needing new sparkplugs (they were fouled). It took the entire time from 10/69 until 8/70 when I left there for it to reach 300 miles (and I lost track of the sparkplugs) for the initial tuneup. The manager told me the guy was starting it with the clutch pulled in, riding it to work (3/4 mile from his house) and home again in 2nd gear, never over 30 MPH. The bike had been dropped on both sides when I last saw it!
Great story. I cannot imagine today a bike shop doing that with making sure a person is the correct height etc.
