just want to run this through some of yas
just starting out riding so not much experiance
went out for ride yesterday in the wind didnt find it to bad even tho
wind was upto 100kph or more
Q i drive a 1300kg 4X4 raised and found that riding the bike was much the same as driving my 4by
the way i look at it the wind drag would be close so just compensated for it like i would in my truck:rockon:

Your truck leans in the wind ?

'scuse the ignoreence but is a 1300kg 4x4 a 4 wheeler?
if so then yeah, the only thing thats different is you're on the bike and will be blowen around, if you took the cage off your truck then it'd be the same...as far as rider goes.

In 37 years of motorcycling, yeterday I experienced a first ever. I actually went round a signed 85 kmh right hand bend at 85 kmh. The only thing different was that I was leaning hard left the whole way round. :gob:

In my view driving an SUV type vehicle in the wind versus a bike is totally different yes you do apply the same principles to try and compensate but when you add the fact that your sitting in a cage with the windows up so your body and head is not being buffeted round!!!! sorta changes the scenario!! every body movement is transferred through to your handlebars affecting the steering ( so i try to release my death grip ) also 1300kg versus 180-200kg of bike + rider??? driving through town at speeds of 50k is also a little different as you were yesterday.... compared to the open road where you are trying to travel at 80 to 110 ... old saying goes though adjust your speed to suit the conditions ...
Not an expert but bike type and riding postion would also make it different mine solid back wheel and lots of panels on the side and a V-twin squeezed into the frame catchs a lot of side on gusts... friends yesterday on different styles of bike all had varying experiences sports bike style ( more stream lined and lower riding postion ) tending to handle the wind much better than cruiser types..... i was the worse i guess back end swerving out at every side on gust and cornering hell lol 60-70 k trying to lean into it but wondering why i'm still upright :innocent: but all great for the experience:Punk:

yes its a 4 wheel drive
i still think there abit the same as with the cage you still have wind resistance eg wind hitting from the side (flat and high off the ground)
will push the truck with the wind
i agree with the afects on a bike where every movement is put thrugh the handle bars but i found that you have to compensate with the truck the same as with the bike
i went along the same bit of rd in truck at the same speed and had the same pushing efect and fish tailing
but i do know its very wered riding on a angle on a bike lol

just been thinking and yes different on a bike but some things can be used to antisipate what the wind is going to do
eg this dot is bike with me on it at 220kg . and this is my truck at 1300kg []
wind is to the side . and [] surface area to weight is abut the same to scale so wind has similer efect you still have to counter the different wind blasts
if the wind to the side is 100kph you have to lean to compensate and with
4x4 you have to steer to compensate
wind stops both have to counter it and antisipate whats gonna happen next
this is just a theory

...surface area to weight is abut the same to scale ...No, surface area to weight isn't the same scale: The bike rider combination is around 1/10th of the SUV, but the effective wind-surface area is around 1/5th. The other big difference is that the SUV uses the tyre friction alone to stick for steering, while the bike must use lean angle. The rider must react much faster than the SUV driver to changes in side force due to wind.
