Gathering parts for the retro supermoto build... Still have an Acerbis crf450 rear fender on the way. Also got a quote from a local wheel builder for the front wheel; $120ish for labor and spokes. As for tires going with a 110/70 michelin pilot power front and for the meantime keeping the 16" rear rim with a michelin city grip scooter tire in 140/70/16. Tires should be around $180 for the pair. Keep you posted!
