Bike handles fine.
Dry roads, it is a bit wobly at speeds over 90 km/h due to the spikes. Icy roads with around 2mm solid ice, bike moves like a train in similar speeds. On snowy roads, rear tyre holds fine, front tyre is not quite to my liking, it has a slight tendency to sideslip on slow speed. Does not matter though.
Best way to drive the bike is to keep it rather upright, have your weight at front and let the rear slip the same way as with the dirt track bikes. Plenty of fun... and not any colder than snowscooters.
I got the bike a few weeks ago, have cumulated now on it 800 km in snow & ice, and it is my intension to drive best part of january... after my wife returns to work... and before I do.
Bike has raised suspension and seat, special tyres, engine and battery pre-heating, battery tricle charging, light shutoff, heated grips, custom made seat and drag type hadlebars etc... but nothing major.
It is the most fun I have had on two wheels for long time... and I will keep you updated as the miles accumulate.
strongly recommended...
