Hello can we put sm bikes pack from mx bikes into gp bikes??
Aprilia (http://forum.piboso.com/index.php?topic=3011.0) and Kawasaki (http://forum.piboso.com/index.php?topic=2316.0) were made for GP Bikes beta7b, but I'm not sure if they are currently compatible with beta8.
MX bikes not compatible with GPB.
You can use tracks from GPB in MX to ride SM in MX ;D
