Of course it's tuneable, lol! Every scooter is tuneable, but it's just f**kING hard to tune a Speedfight and if you tuned it, you won't get the same performance as a Zip or Aerox.
I drove on a Speedfight, it sux and it's not tuneable.
What?
If you really want to tune it with great preformance, it's no problem.
Tuning it is not the problem here, i belive Doggi wanted to drive it legaly, aka no extra tuning
