2012 Yamaha YFZ 450

It’s understandable that a lot of people are turned off by high-priced purchases. Given the state of the economy we’re in, saving as much money as you can has become a great priority.

Motorcycle brands like Yamaha know this, and they are certainly sensitive to the market’s capabilities. That’s why it has become important for them to release models that are not only economical when it comes to fuel, but also on the bank account.

One such model is the 2012 Yamaha YFZ450 , an all-utility vehicle that’s considered one of the best bargain buys on the market. It’s got great styling; it has an excellent chassis design; and it comes with an impressive 449cc 5-valve DOHC power-plant.

Among the new features of the 2012 YFZ450 model are a new pair of high quality, non-reservoir shocks made by KYB that have been tuned exclusively for the YFZ and designed to excel at handling a wide variety of riding situations. The bike also offers significantly more low and midrange performance compared with the previous model. Yet despite this, the 2012 model still carries the same power output, thanks to a few Yamaha modifications that include revised cam profile and timing and new ignition mapping.

As far as the chassis is concerned, the new YFZ450 has a lightweight, ultra-compact steel frame with an aluminum sub frame that gives the machine added flexibility. For the rear suspension, a highly tuned Showa piggyback shock returns on this newest model, with the only difference being found in the adjustability features.

Other new features attached to the YFZ450 include a new push-button ignition, tapered handlebars, and an efficient dual-hydraulic braking system in the front with two-piston caliper in the rear.
