Howzat from South Africa. I needed you advice as i want more power on my VFR 400 NC 30. What sprockets can u se on her for better performance and power?

to increase acceleration, but decrease the top speed put a small one on the front and a bigger one on the rear

Thanks i need more top end as i use here for long distances.

so you want more that 112MPH, looking to loose the licence then

if its delimited more like 125 ish

yeah mines delimited and ive seen 130 on mine beside my dad in his audi s4*.

so around 125 true speed?



*Private roads obviously.

On the top speed run i did last month, i got 136.9mph at the redline (dyno speed) but my speedo was reading just over 145. So mines out by around 8-10%. Assuming yours is about the same, between 120-125 sounds about right.

Blimey.

To be honest, Dyno top speed runs are pointless. You've got to remember that on a Dyno the only acting resistance is the technicians body weight, rear wheel, and thats pretty much it. Theres no wind resistance, front tyre friction, road resistance etc etc. Probably 130 true speed if im lucky!

Sounds good though.
