Well for f@cks sake Dirk! I live in stockholm and i have 2 bikes, You should PM me and Ill hook you up.
There are some really nice roads around Södertörn (check road 257 from "Rosenhill" to "Västerhaninge" called "slingerbulten
Kartor, vägbeskrivningar, flygfoton, sjökort & mycket mer på eniro.se) and i can show you around some if you want. Roslagen up north is bikers heaven aswell!
A word on the behaivor..
Sweden doesn´t have nearly as much police on the streets as they do in the US, so getting caught is more by accident then the fact that police actually monitor the behaivor as such.. Police are trained in the academy for a minimum 3 years and then 2 years probation and that is just the basic police assistent, so getting new cops out on the streets demands a longtime in training.. And then there are budget cuts. Good thing is that they are generally very proffesional
But like you said..
wheelies - Happens, but it depends on where you are.. Not as much as it was
excessive speed - This is a problem since police dont have large manpower. Police also have orders not to chase bikers if they run, because of the high risk "not worth the possible accident" is the reason the police leadership says
lane splitting - Legal in Sweden for bikers
riding on the shoulder - Also legal in Sweden for bikers if there is congestion. Max. 70 kph
other bad behavior - Comes back to police manpower again.
Most of the crowd i ride with are 30-40 years old and we ride hard on the track, but not on the street.. Mostly that is tha case with serious bikers, but just like everywhere, there are bad seeds.
Shoot me a PM! I´d love to get together for a cold one or for a ride!
