It would need to be a particularly shite P200. They're not powerful enough to pull 4.8 gearing. On the standard gearing, you're revving the knackers off it at 90km/h. You'd be better off with a decent kit, and upgear it.
The only way it'll have comparative performance to a P200 is to get an indian speedo.

I suspect you are right Muttley, it's for my son so I'm quite happy that it will be slower
