SF1 Gearing Help Please (or take yer bike for a ride)

[Harry Lime]

I've forgotten what gearbox / drive sprocket is on the SF1....and can't be arsed to take the cover off to find out. But this evening it felt undergeared.

So could someone with an SF1 on standard gearing tell me what revs they're pulling in 5th gear @ 70mph (for the imperial folk) or 80kmph (for the metric folk) in whatever gear.

I'll work it out from there....

Thanks

H. Lime.

it should be 19 front and 40 rear, a bit out I know, but you should be bang on 80MPH at 5,000rpm.
