The thing is this.
Variation and trans tuning/gearing is one of my favorite arts.
That's been my secret to my bikes.
There's so much hp left over and wasted from a non modified or partially modded transmission. By changing the rate of the rear pulley's tension, and really maximizing its travel, and maximizing and modifying the front variator and fixed cheek for how deep the belt can drop in at rest, you can gear insanely tall and still get off the line like a rocket.
On my lil 50cc hobbit, i actually modded the rear pulley to the point where it's geared way too low.
Belt can stick out of the rear by like 4-6mm. It's crazy.
So when you take off, it actually takes a second or two for the belt to travel the distance it needs to where you can feel any acceleration. Didnt leave it there of course, but it's an interesting observation . Maximizing the variables!
By throwing gears in a bike that can adjust its variation so low, low end would not be lost at all, and as long as the power is there and the trans is tuned appropriately, you'll rip right to the top. It's just like some of those dudes that preach crazy high gearing but are slugs off the line. (Pete N? Idk) If you can get off the line fast with crazy gearing, the bike will get to top speed for sure as long as the trans is tuned right.
And all of this talk so far doesn't even bring stroke into this. PP Derbi is basically a hobbit with a 4mm stroker. So much torque to use in that cranks massive stroke to push thru whatever gearing you want.
I don't run bikes that rely on extreme rpms to get to top speed with low gearing..
Not my thing. Don't like ripping around on a dual variated bike that stays at 12-13k all the time. It's super annoying. 11k is about max I'll go.
Will say that I'm not a racer, won't ever be....but I do like to put the hammer down on rides, but I've got my style and really like it.
TLDR, tall gearing on variated bikes is GRRRRRRRREAT!
