A: Yes, in some ways. But, 2017 yz250f, it is quite a bit different in the power department. Last year the only performance upgrade that Yamaha made to the YZF was the oversized mm front rotor.

Since Yamaha did a complete overhaul on the YZF in , this bike has nearly taken over the class winning four out of the last six championships with Cooper Webb and Jeremy Martin. The rearward slanted engine and reversed cylinder head design has proven to be a very powerful package. Yamaha focused on increasing its performance and durability for with a host of changes. For , Yamaha focused much of their changes towards improving the already incredibly fast engine. Many of the changes like a larger midpipe are geared towards improving the mid-to-top performance. In addition to updating the throttle body joint to aluminum to transfer heat from the cylinder, they also gave the engine cases a heat treatment and utilize a stronger connecting rod to increase durability. The cylinder head port was raised 4mm providing a straighter intake while a 15mm shorter air funnel inside the airbox increase the airflow by a claimed 4. This gives the increased flow simulating a larger valve. They also came up with a new ECU calibration to make it all work together. Not only did Yamaha alter the power output, but also the shifting performance and a smoother clutch. They added a bushing on the shift arm inside of the engine case as well as grooves in the shift cam to add oil supply for less friction. Lastly for the transmission, 1st, 2nd, 3rd, and 5th gears were widened and the shifter position was lowered 5mm to match the frame changes. The footpegs are now 5mm lower due to the new frame consisting of steel engine mounts and a 12mm expansion to the forging above the footpeg and housing the swingarm pivot. It is the exact same frame as its big brother, the YZF. They also chose to stick with their famed Kayaba SSS spring forks rather than heading to air like most competitors have.

Carburetion Brand. For Yamaha increased the tubing diameter by 2.

Chassis - Handling Balanced feel. Of course, the added lift requires stiffer valve springs. Improved power and handling. Rear Suspension Material. Front Central Suspension Strut. You can also lower the oil height in 5cc increments until the desired performance is met. As a rule of thumb, we ran less compression damping than stock and more rebound. Manufacturer Recommend Minimum Age. Yamaha Dealers. They work well together and has a neutral feeling at all times. Trying to knock it off the top step is going to be hard work for any manufacturer.

Sometimes the scale weight and the feel are very different. A: The hate list: 1 Air filter. Appealing to riders of all speeds and sizes. Battery Warranty Months. Motor compliments the chassis. Compression Ratio. Small fork changes really gave the shock a better feeling too. By shortening the clutch-actuation arm where the cable connects 3mm, straightening the cable interface at the bracket and changing the cam ratio from 4. The pull into the top never really drops off. More room between the plates lessens clutch drag, slippage and wear. The larger the diameter of the head pipe, the greater the top-end power the smaller, the better the low-end response.
