Ben Bostrom Events

Ex-racer Ben Bostrum might have stopped competing on motorcycles, but he hasn't given up his passion for two wheels. He's teamed up with motorsports promoter M1 to create Ben Bostrom Events, a company that plans to host world-class cycling and running races across the US. According to a press release, the high-intensity events will feature an 'entertainment-filled atmosphere', combining many of the familiar elements found at other MOB (mud, obstacles, beer) racing events.

Yamaha WR450F 2016

In addition to introducing a new two-stroke model, Yamaha has updated its flagship 4T enduro, the WR450F. The motorcycle used the YZ450F motocross engine layout with the cylinder turned back and the intake and exhaust turned 180 degrees. The engine is housed in a new aluminum frame based on the aforementioned YZ450F.

Yamaha’s reason for doing this is to shift the heavy end of the motor more to the center of the motorcycle to make it more agile and responsive.  Slanting the cylinder also made for a straighter pathway for the air intake at the front of the bike.
