  1. Big wheel 80 is still smaller than a full size bike.My 10yr old has had a big wheeled 80 for about 18 months, my 8 yr old rides a medium wheel. They are virtually identical in size and weight, (other than seat height, due to smaller wheels) Looking at your lad on your Scorpa. I think a big wheel is the way forward.
  2. Thanks for the response. KTM engine is the same as the Beta minitrial (automatic). but not the geared Rev 50. I know Vertex pistons used to supply beta uk. I have emailed them but no joy.
  3. Does anyone out there know of an alternative piston for my lads Beta rev 50, 2002 four speed. Beta uk say the piston is now obsolete. A big problem for any older rev 50 owners.
