Inside the 2012 Yamaha TT-R50E and PW50 - Dirt Rider Magazine

Chris Denison

Without going into a long-winded rant about government regulations, let's just say that Yamaha recently had the great pleasure of re-releasing two of their most popular models, the TT-R50E and PW50. Together, these bikes represent the ultimate entry-level two-wheelers, and both air-cooled powerplants are reliable and tough steeds for any aspiring young rider. In fact, if you were to poll today's top pro racers about which bike they learned to ride on, the majority would undoubtedly cite the PW50 as their first-ever bike. That trend may still be the standard, although the inclusion of the four-stroke TT-R50 does give you riders another option in pint-sized performance.In person, these bikes may not look that different; they are both little, blue and super fun looking. But on paper, the differences are vast and the distinctive character of each bike can really be seen. We're still waiting to get our hands on these fifties for a full test of each, but the following chart can really give you an idea of where each blue fifty shines:

Dirt Rider's opinion: No matter how big you are, this fun four-stroke is a blast for both kids and adults to play on. The electric starter is awesome, and although the stock bars aren't the best things on earth the entire bike is actually pretty durable.
