I have a nice Powell Challenger for sale. The bike currently has a newer 4-stroke engine in her. The original owner also gave me the original tecumseh engine with serial numbers, original Powell Quick Release Throttle assembly, original Powell exhaust with Spark Arrestor, original wheels tires etc.etc...Bike is in good condition with good chrome, with a straight frame and fork! You can ride her as-is or restore her to a complete original. This is a good one....asking $575 in southern california....
