Cheers guys, the pw50 are way too short feet up fun, but the pw80 look really close, length is about right and with a quick tape measure rhe ty forks came up about 25mm so pw80 at 26mm is dam close, very little mod needed- the location of the spindle is off set in front of the forks where as the ty is in line at the end of the fork leg so how much this may alter the trail and rake I'm not sure but dam close, cheers mcman56, see if I can source a UK supplier, stripping forks is something I've not attempted and bit wary of- Iknow you guys don't need me to say this but ty80 what a beautiful bike for a kid to learn on, my dad never got me one in the 70s and getting this for my lad is as much for me as for him,. Cheers all much help.
