Whether it is me or Guorui classmates, when we rode, we still found a problem, the Wuji 250RR pedal position is exactly at the rider's foot, so in fact, we can only deliberately avoid the foot pedal part, put the foot forward or backward, but this will be very awkward, more difficult to settle down, this problem is particularly troublesome for my height.
The soHOC structure single-cylinder engine equipped with the infinity 250RR, the overall output bias is biased to low and medium speeds, such a tuning is very useful for this small track, the oil after each corner can provide very good power, and the car can get 20N .m of torque at 3000 rpm, and then all the way up, at 7500 rpm to reach the peak torque of 23N .m, so the entire available torque platform is very broad.
It's just that fish and bear paws can't be combined, which pays attention to low and medium twists, and the power ductility of the infinity 250RR high speed will be slightly inferior, mainly after 9000 rpm, the vehicle appears to be a little weak. Fortunately, the track we ran didn't have too long straights that required the car to play a high-rev. Feedback to the daily driving environment, stronger low twist is obviously more suitable for stop-and-go, street-to-street urban road conditions, of course, it also reduces the probability of newbie friends starting to turn off the fire and cause embarrassing situations.
The tires of the front 110 and the rear 150 are matched, and the visual effect is great. However, compared with the 140mm width tires commonly used in the same class, the rear wheel will still be slightly slower when dealing with the S-bend fast turnover action. In the state of grinding to the foot pedal probe, the rear wheel still has a width of about half a centimeter or so that it is not used, that is, the inclination limit of this tire is actually greater than the body limit inclination, and it can also be said that the height of the foot pedal after compromising on comfort limits the vehicle's play.
The adjustment of the front and rear shock absorption is sporty, which can provide very good support in the corners, and with the cooperation of the frame, the vehicle's trackability in the corners is good, and the fuel tank clamping feeling is also very good.
Although the brake feel is a bit blurry, it also provides effective braking force when re-braking before cornering. And with the cooperation of this set of adjusted movement of the front shock absorption, the body will not have too many nods, ensuring the stability of the body before entering the corner. In terms of my driving intensity, there was no thermal decay in the brakes
Although the Infinity 250RR is equipped with a single-cylinder engine with SOHC structure, the actual vibration suppression is even better than that of some cars with DOHC structural engines of the same displacement. Its main vibration occurs after 6500 rpm, concentrated near the fuel tank and saddle, and the vibration frequency will be strengthened as the speed rises, while the handlebar, rearview mirror, foot pedal and other parts of the vibration are well suppressed.
