So I convinced my old boy to get a license and gave him my old bike, a Kwaka GPX250. finally caught up with him to go for a ride, all was going well few wobbly bits but nothing to be concerned about. Came to a give way, on a slight incline, stopped, checked traffic and he gave it a bit of go. Now the 250 has no power what so ever, he's a big bloke (100kg?) anyway turning right the front slipped out from under him and down he went. He's ok, the bike has a broken RHS footpeg bracket but for the life of us we're not sure what happened. There was a tiny bit of oil near where he started turning but i doubt it's that. He thinks he gave it a bit to much go and lost traction on the front wheel. The 250 has bugger all power, i'm a bit skeptical but keen to understand what happened. Any ideas?
