Rob was breaking in his new 2010 YZ450F today in the Nevada Desert. He wasn't on the throttle more than 1/2 to 3/4. There were times I was having a hard time keeping up on my RMZ450 at full throttle. In video 05 at about 5.30 minutes I take a bizzare rock hit to the temple while recording. How that rock made it between my googles and helmet was very strange! http://vholdr.com/node/52784 http://vholdr.com/node/52785 http://vholdr.com/node/52786 http://vholdr.com/node/52789 http://vholdr.com/node/52795 http://vholdr.com/node/52801 Rob let me ride his new steed. The fuel injection was very linear and a smooth power delivery. You didn't realize how fast you were going until you apllied all the brakes almost locked up and you were still going to fast to make the turn! The bike handled very well and turns as well as my Zooks! Overall I was very impressed with bike! Yamaha is also offering a warranty for the duration of the financing agreement for a few extra bucks a month. The only thing the warranty doesn't cover is clutch components and tires. A great deal if you finance!
