My opinion about this four track is really positive because y think it is the best one for racing in traks and in any kaind of environment , it is extremely  fast and forcefull  yust because his 450cc motor. It is in short words the best one of the fourtracks it is perfect.  

Displaying the technical part of the vehicle we are faced with an ATV that can exert a displacement of 449 cc DOHC 5-valve, besides you can also talk about transmission of 5-speed transmission. With respect to characteristics such as its dimensions are 72.4 x 46.1 x 42.9 inches and about the capacity of the fuel reaches 2.6 gallons.To respect the weight, this is 385 pounds.

The ATVs, also known as quads, quads or ATVs are as you know four-wheeled vehicles, similar to a motorcycle, but they have four wheels, to provide better stability and security especially in rough terrain. Such vehicles are highly used in sporting, recreational and agricultural, thanks to its good performance, reliability and response to different demands If you want a good alternative, we recommend the Yamaha YFZ 450, which from what concerning the design seeks to provide a fresh alternative, modern and even some youth. The same also you can select the colours, can selected, finding the black metal, white with graphics, electric blue, among other cases.  

CT Racing has uncorked the power that is available with the awesome YFZ450 motor. You can see from our dyno chart posted below that we have considerably more horsepower at every RPM split as compared to stock. The Sonic pipe is not a top end pipe. We really go after bottom and mid. What we have found through our R&D process is that we still end up with more peak horsepower than our competitors pipes, and the highest horsepower producing pipe on the market. This has been proven in three different Dirt Wheels Magazine pipe shootouts. Our kit is plug and play, complete with jetting and tips for air temp and altitude correction. We highly recommend the addition of the Pro Design Prow Flow filter system for maximum performance.
