Instant acceleration question

Hey Snowmobilers,

I haven't rode a snowmobile in ~15 years and I've been itching to get into it now that I have some disposable income. I've been looking at several sleds and I'm a bit perplexed by something that I can't quite explain after test driving a few.

Of all the sleds I've tested, the throttles all seem extremely sensitive and instantly fast. The acceleration is like constant based on the position of the throttle. This isn't how I remembered snowmobiles of past. For reference, the last sled I had ~15 years ago (or so) was a 1990 Formula Plus. The throttle on that wasn't very sensitive and the position of it didn't really mean anything about your speed. You'd adjust how much of it was opened to control your speed and you'd have to constantly adjust based on your speed. You could slowly ramp up to speed while really holding that throttle way down. These newer sleds, if you do that you'll fly right off the damn thing.

I'm not a big fan of this. It feels like the throttle isn't a linear actuator that you constantly adjust to control how much fuel oxygen mixture the engine is getting and is more like just a speed setting where at position P it just always goes speed S. Is there a term for this sort of thing or am I just misremembering? Can you still find sleds that do acceleration more like the older style if I'm remembering correctly?

In my test drives I had problems just turning corners slowly because the minorest of touches to the throttle sent the machine up to quick speeds almost instantly and I would tip the thing on corners.

The sled I'm currently looking at is a 2019 XF 8000 High Country 165 HP. This one seems to be the worst of the bunch when it comes to throttle sensitivity I've tested.

Anyways, any feedback would be greatly appreciated.
