Backyard Bonanza: Bonanza BC 1200 Mini Bike

Back about 25 years ago, kids were actually permitted to go out outside and play unsupervised.  The coolest kids had parents that bought them minibikes.  The bikes were simple tube framers, powered by an old one lung lawn mower engine.  But what would happen if you put a racing go kart engine in your mini bike?  Find this Bonanza BC 1200 Mini Bike for sale in Kent, WA for $1,250 via craigslist.

Bonanza was a full range manufacturer of mini bikes back in the 1960’s to 1970’s, selling both assembled and kit bikes.  The BC1200 was their mid-range model with an actual front and rear suspension.  This BC 1200 has had a Briggs & Straton Raptor 3 motor, put in it.  The Raptor 3 was the 3rd and final generation of Briggs & Straton racing’s one lunger.  Out of the factory, it produced 5hp and was popular with go karters and junior dragsters.  Tuners are able to get over 8hp of of it, but even with stock power, in a mini bike frame, this must go like a bat out of hell.

Obviously the subject of a restoration (many new parts the seller says), no mini bike I remember from my youth looked this good.  As the seller says:  “This is a big mini bike fast and powerful. This is not for a beginner it is way to much power for a young kid.
