Well, I couldn't help but investigate (sorry). Pics from the Kawa site, doctored by me.
What's the same:
- seat to footrest distance (blue) - possibly slightly less on the H2 by 1-2cm
- seat height to ground, surprisingly
- headlamp to ground
What's different:
- H2 footrest is slightly further back
- H2 handlebars are very low
- H2 top of the fairing is very low
So, desperately trying to get back on topic, you'll definitely need to buy Helibars for an H2.
And I may yet try an H2 SX out. Once you've done the relaibility test, David.
