Motorcycle handling difference's

[GfromLT]

Hello,
Im brand new rider (probably have around 20 hours of riding under my belt). Im located in eastern Eu and recently finished my courses and passed my riding exam second time (yay!) and it kinda does have something to do with my question:

Why would same model bike handle differently?

Basically both the driving school and exam center use the same model (not same bike) yamaha xj6n made from 2009 to 2015.

School bike was handling really well, last few practices I could goof around on it. Most importantly, if I was turning handlebars a bit and let it go, it would straightened it self out.

In contrast, exam center bike, although looked the same and was exact same model, was really different. A little turn would make it turn even more with comperatevily high force, as a result it pinched my thumb between handlebar and gastank. I was shocked, couldnt and cant understand why, where do the difference come from? Does majority of motorcycles handle like this?

Tyre make, tyre wear, suspension setup, ride height.

What you describe with the steering sounds typical of what would happen if there was a discrepancy in the front to rear ride-height with the front of the bike lower than it should be relative to the rear causing a steeper rake-angle. Either due to the front end being lower or the back end being higher than the ones you are used to. This tends to make the steering feel faster and the front end has a tendancy to "tuck in" to corners.

Potential causes include different tyre profiles, different shock preload, the position of the forks in the clamps or potentially the use of lowering kits (more likely on the ones that were less responsive to steering input).

Low tyre pressure, especially on the front can also cause this kind of feeling.

Do you have to use the exam center bike or could you use one of the riding school bikes for your test?

How do you plan on insuring it without a full licence for the bike

Sorry I thought you were talking about using a different bike for your test.

Sounds a lot like the guns at the target shooting booth at the fair, slightly bent barrels For some reason they all got upset when I pulled out my AK47

Driving school vehicles take a hammering too so perhaps the bike was broken somehow. I had a similar thing when I learned to drive. I was using the schools car and couldn't get on with it. The clutch was heavy and snatchy and the gearbox was vague with wobbly springs and worn gateing. It was like driving some sort of comedy clown-car.

I got fed up with it and took my own car to the next lesson, the instructor told me to put in for my test immediately, which I passed.
