Sym Jet4 125cc

Evening everyone.
My first post in the forum.

I am buying a brand new Sym Jet4 125cc and was wondering about how long and what speeds I need to be done to "run in" the engine?

Any help would be appreciated.
Thanks

 

Half throttle first 300miles or so at a guess

 

As said, don't thrash it to death, let it warm up a little before starting off, just be easy with it.

 

Once run it should do low 60s fine. I did once take it down a very big hill and get 72mph lol
