Just to add, the Speedfight is the Saxo of the 50cc world so any secondhand one is likely to have been run full bore for most of it’s life.
So will any moped, the throttle may as well be an on/off switch for all the power they have. I had a cheap Chinese one for a year, blew it’s piston rings, stuck a new piston/rings/barrel in for <£90 and kept going. Out of our group of 10 or so the only failures were either ‘tuning’ related or the result of one too many trips down the road, I don’t think any of them died through natural causes.
If he want’s a Vespa style one then it’s as good as any.
I’ll probably get flamed for this but I hate peds! I see kids round here just being dicks on them. Lad died 200 yds down the road from us just over a year ago. He was 16.
I’d much rather see folk get true road sense in a car before having to deal with the bad drivers that frequently kill cyclists let alone young lads doing 40 on a pedder.
It’s barely faster than a push bike and the riders wear proper helmets and jackets, it’s not safe, but it’s no worse than this forum’s raison d’etre.
