    Yeah sounds like wheel spin to me. Ive done many wheel spins in the wet and generally speaking they will stay straight and feel like clutch slip (on my latest bike it actully was clutch slip, untill i replaced it) I dont recomend it, because "sustained loss of traction" is instant impound vehicle and license loss too i think, But coming around a low speed corner onto a striaght, lean forward to lighten the weight on the back wheel, bang the throttle on and clutch it, can do 'fish tails' for quite a fair distance that way. Do make sure you keep the throttle on, that way the fish tails slowly get smaller and smaller untill you grab traction. If you back off the gas during a wheel spin, thats when the back wheel is likely to step out and try to pass the front wheel as they say. Pretty standard sort of thing if you ride a dirtbike, they are always getting the back wheel spining. Unlike a car you actully steer the bike with the back wheel, sounds odd i know and ill problery cop some flak for it, but as an example dirtbikers often get around a corner with the front wheel in the air, the lean angle on the back wheel does the turning. Problery said too much, so thats enough from me.

    I did that once while overtaking on a wet road. I hit the centrel-ine at full throttle doing 130km/h and unhooked the rear wheel.

    Didn't crash or massively unsettle the bike, but it really wasn't a nice feeling.

    Have managed to experience this on the 250, coming back to Napier from a weekend in Wellington on the Takapau road which is slick tar with no stone chip in the wheel tracks in most places.

    But with relativley heavy rain. passing cars the rear tyre would spin up at about 110 across the line and wallow left and right in the other lanes wheeltrack. Thought it was pretty funny at the time, passing cars in a squiggly fashion.

    "Wheelspin at speed" is when David Jefferies talks (talked) about flying across the top o' the Mountain at 140mph, rear spinning up at will.

    Watching them boys go thru' Glencutchry Rd in the wet is incredible;come past, sligthly leaned over, bikes squiggling side to side, power stays on, lean right then left then off away down Bray Hill.

    But yeh, sounds like you got the right kinda spin

    I'm curious as to whether the below experience is likely to be wheelspin or the bike popping out of gear?

    Any ideas on this?
    If it popped out of gear you would have needed to pop it back in.
    If it is a newish bike,the speedometer pick up is reading off the engine drive sprocket so the speedometer would increase as would the tacho with no extra forward motion if there was loss of traction.

    Wheelspin in the wet,try a CBX1000 with 105hp at the crank and a 120 rear tyre,you could light them up in the dry also coming out of roundabouts.

    Another good one is aquaplaning on the motorway.
