Hey Tubsta, I am just looking for another 10-15km top end speed .. the orbit just wont go the speeds I am after apart from that I love it... sits on about 80-85km .. have a limited budget cause I only use on weekends and on scooter rides... So really its just a toy..
Ahh, we all have to have our toys, that is why I have a TGB R50X in the garage. Perfect for, hmm, just going to the post office?

A pretty cheap mod that you could do that will get you close to your desired top speed would be a slightly heavier roller. If you have someone that has the right tools and is handy with them or maybe during your next service, you could try that one out. A set of rollers should be no more than $20.
