F at the top of the 4. After a major revamp in 2. Yamaha boasting a 3. YZ4. 50. F unit sales year- to- date compared to 2. The 2. 01. 5 YZ4. F is currently the best- selling 4. Earth. But as good as the 2. Yamaha has found ways to make the YZ4. F even better for a wider range of riders in 2. The 2. 01. 6 YZ4. F is still fast, but it is now easier to ride than ever, and it handles better than the 2.

Yamaha Reviews The Japanese company was well known for its musical instruments, but in 1955 it began producing motorcycles. It began with simple and inexpensive. If our day spent aboard the 2. YZ4. 50. F during Yamaha’s U. S. The revision list in 2. ECU tweak (to fatten up its fuel- injection at low rpm for a smoother throttle feel), bigger valves, lower motor mount changes, a slight gearing change, stiffer fork springs and suspension setting refinements. For 2. 01. 6, Yamaha has refined the engine even more, retuned the chassis flex and juggled the suspension damping specs again to make the brutish 4. But there’s also a new trick in the form of a new Launch Control System to help harness the 4. The 2. 01. 6 YZ4. F engine has received new camshaft profiles to improve its low- end grunt without sacrificing mid- range or top- end thrust. The key to making the YZ4. F’s 4. 49. 7cc, liquid- cooled, fuel- injected DOHC engine a bit more usable for vets and less skilled riders lies in the cams. The engine’s 9. 7. F’s titanium intake and exhaust valves open and close. According to Yamaha these are the specs for the 2. YZ4. 50. F Intake Cam. YZ4. 50. F Intake Cam. Open: 3. 7. According to our ace test rider, Ryan Abbatoye, the 2. YZ4. 50. F now comes off the bottom smoother and with more authority than the 2. The extra grunt also makes for a more seamless transition to the top- end rush. The slightly less explosive power delivery at low rpm should increase confidence in riders making the transition to the YZ4. F, but pros needn’t worry about a lack of sizzle. Abbatoye said that the bike feels just as strong through the middle and on top as last year’s YZ. The only difference he noted is that the 2. Still, the YZ4. 50. F delivers more power than most mortals can tame, and the slightly abnormal Abbatoye amply showed off the bike’s true potential as he nuked berms and soared off of Comp Edge’s numerous jumps. The Yamaha is clearly still a beast, just a more manageable beast. The YZ4. 50. F is easier to ride than last year’s model, thanks to its meatier low- end torque, but test rider Ryan Abbatoye noted that the 2. Yamaha also made improvements to both the YZ4. F’s clutch and five- speed transmission for 2. The new shift stop lever increases spring load by 2. Yamaha says will make shifting more precise under power and also reduce the chance that the rider will catch neutral on the 1- 2 upshift. We never had an issue with the way the YZF shifted in 2. Abbatoye noted that the 2. The only other internal engine change Yamaha engineers made for 2. Yamaha’s new Launch Control System works well on slippery concrete starting surfaces. The system is activated via a button on the handlebar. Once in use, it reverts back to the main engine map as soon as the rider hits third gear. The YZ4. 50. F’s new Launch Control System is designed to offer the same benefit as the systems found on competitive models – to get the rider out of the gate more effectively. The system works in concert with the ECU to briefly retard ignition timing and thus limit wheelspin on slippery concrete or slick dirt launch pads. It is engaged by pressing a button on the left handlebar, and a flashing red light denotes when the system is armed. The system works in either first or second gear, and the ECU reverts to the standard map when the rider shifts into third gear. Abbatoye spent some time getting to know the 4. F’s Launch Control System at Comp Edge. On the track’s slick concrete starting pad, the LCS made second- gear starts easier, and the machine moved out more quickly than it did when Abbatoye made his baseline starts with the system disarmed. However, in the dry, loose, deep, dirt just ahead of the starting gate, the system tended to flatten out the power too much to make it truly effective. Abbatoye found that he was better off simply using the old- school, slip- the- clutch method to control wheelspin rather than relying on the LCS to do it for him. The Launch Control System certainly works when conditions are really slippery, but we’d call it a qualified success. Yamaha tweaked the YZ4. F’s chassis to improve its handling characteristics for 2. Bilateral Beam aluminum chassis but also adjusting the fork offset to deliver more front- end feel and better turning stability. To attain the desired rigidity, the 4. F’s frame spars have been made 1. Lastly, Yamaha incorporated new footpegs that are 5mm lower than the previous models without actually changing the footpeg mount on the frame. This was done to increase rider comfort and also, says Yamaha, to lower the YZ4. F’s center of gravity. With its improved front- end feel, the YZ4. F allows the rider to rail through rutted corners and attack berms with confidence. To directly address the front end feel in the corners, the 2. YZ4. 50. F gets a new top fork clamp with 2. However, at the same time, the rear shock spring is softer – Yamaha dropped its spring rate from 5. Nm to 5. 6Nm, effectively allowing the rear end to settle more under a load, which actually increases trail. The 2. 01. 6 YZ4. F’s 5. 8. 3- inch wheelbase is the same as last year’s bike. Abbatoye, who weighs 1. Whereas last year’s model tended to sit with more of a tail- high, stinkbug stance, the 2. While we noted a slight nervousness in the 2. YZ front end when diving into corners, the 2. Abbatoye was able to charge the corners harder because the ’1. It also dutifully follows deep ruts without any issues. The 2. 01. 6 YZ4. F’s suspension feels more balanced than last year’s model. Yamaha fitted the ’1. KYB shock with a slightly softer spring to create a more harmonious suspension feel. The spring change to the YZ4. F’s KYB piggyback (which offers preload, high- and low- speed compression damping, and rebound damping adjustability) shock also yields a more harmonious interaction between the front and rear suspension in rough ground, with 1. Up front, Yamaha has stuck with its tried- and- true 4. KYB Speed Sensitive System (SSS) fork, which features good ol’ steel coil fork springs, instead of air to deliver 1. The fork is easy to tune and offers ample compliance over small bumps while resisting bottoming over big jumps. The revised suspension and chassis settings had our test unit tracking straight and true through Comp Edge’s whoop section. Yamaha has increased the front brake disc size to 2. We didn’t notice any major improvement over the previous 2. The 2. 01. 6 YZ4. F’s new 2. 70mm petal- style front disc brake is about the only improvement that leaves us indifferent. While it is 2. 0mm larger than last year’s front brake, Abbatoye said that he really didn’t notice any increased performance out of it when compared to the previous front brake. The brake delivers a linear feel, and its stopping power is more than adequate, but it’s nothing that is going to make Honda or KTM run back to the drawing boards. Then again, maybe the 4. F’s ergonomics will. Yamaha’s strict attention to mass centralization allows for a roomy cockpit with a flat, narrow seat and practically seamless transition to the top of the “fuel tank” (which is actually the top of the airbox, since the 2- gallon tank is under the seat). Abbatoye quickly noted that lowering the footpegs 5mm makes a substantial difference in comfort, allowing him to feel completely comfortable when whipping the bike around to his heart’s content. We dig the 2. 01. Yamaha YZ4. 50. F and predict that it won’t be easy to topple from its throne as the king of the 4. Yamaha has chiseled away the YZ4. F’s rough edges over the past year, making small improvements that have increased its performance and its popularity. The 2. 01. 6 YZ4. F is proof that you can make a great bike better.
