Very soon, the time will come when kids grow up without ever riding a two-stroke motorcycle. With its new CRF150F, Honda has accelerated that timeframe by being the first to produce a race-ready four-stroke intended to replace its 85cc two-stroke motocross bike. The company is hoping this transition will take place as quickly as it did with the bigger Thumpers, which needed only a few years to take over the two-stroke market in most racing disciplines. For 2007. Honda is selling both the 150 and the CR85R but will drop all two-strokes in 2008.
