That speed increase over the standard almoust sounds unbelivable. Is it due to the variator?

I have a 300 with GPR-Pipe, PM-tuning ECU, Mike´s mod, and I would go for the Polini if it would do this huge difference. I only do 80 mph indicated.

The Polini Variator is what allows for the better top speed. It does change the gearing and allow for a greater range of top end speed.

We did verify the additional speed on both the dyno and the freeway. I think a windshield helps too.

My mechanic said that the Polini Variator plus 12.9 gram weights made the best difference in power and top speed.

I have a similar configuration "Leo Vince exhaust, Super Corsa Racing Power Booster( PM TFI, in UK), and malossi variator", 15g....
Can u tell me what are the settings on your corsa RPB ????
The standard settings for gts300 for my PMTFI are for PM exhaust that is not the same of LV4road.... im plenty of detonations....
thanks

Our SCR settings have a different baseline setting from the PM Tuning modules, so the settings wouldn't coincide.

Very interesting reading guys. I gained an extra 5m.p.h. top speed with one simple add on. A small cupini screen this must do wonders for the aerodynamics and air flow. My GT200 will do 77mph without the screen and 82mph with the screen fitted. This was tested on a perfect day sunny with no wind and scooter was flat out the road was a 6 mile flat straight. The figures are also gps. My LV exhaust makes no difference at all just looks and sounds better. Ride safe

Have you tried up-jetting your main jet from a 92 to a 95? That should help you get a little more power out of that Leo Vince.

Is there anything that can be done to help a gt200 hold it's speed better on hills. I'm thinking a Polini Variator, and am unsure of the weights! I would like slightly faster acceleration and a lil more top speed also if I can have my cake (or popcorn, since we don't have a cake eating emoticon) and eat it to.

Also, I've read that the Polini Variators don't last that long, how sturdy are they?

In my experience, the variators have held up fine. But they do require more frequent roller changes. Maybe every 3000-4000 miles versus 6000-8000 on the stock rollers. On our 300 super we were able to get better acceleration and top speed with the Polini variator.

They come with 11.8gr rollers which have been great.
