My commute will allow me to do 25-30mph for 12 km, then about 3-4km at 50mph, then back down to 25-30mph for the last 8 km or so, so I hope to get pretty good mileage overall!
Unfortunately I can't switch to Neutral from 4th gear, so can't do any EOCing, which I was hoping to do (I'm still keen to find a way around this). I might use a smaller sprocket on the rear wheel to lower the RPMs a bit, and may modify the ignition timing while using high-octane fuel.
I might also do some small aero-mods on the bike, kind of like a fairing, on the fast stretch of my commute will probably duck down a bit to reduce drag, and will make a rear carrier box for it, which will be aero-designed so it reduces the drag I will cause while sitting on the bike (especially if I bend down a bit).
Also, it has street tyres already, which is nice!
Look forward to using this for the commute
