Buddy Adventuriderz, morning dual sport motorcycle rider Kawasaki KLX 150 would have been very suck if this bike has a very unusual engine specifications. Even relatively inferior when compared to other sports motorcycle in the 150 cc class, both in terms of power and torque generated. The impact what? Of course, power on the bike not so satisfactory, under the power was not impressive.
As a dual sport motorcycle, KLX 150 ngisi power should continue, particularly at lower power to obtain optimum torque and acceleration. In fact, not entirely so sob. KLX 150 in standard conditions is often oversized when crossing the ramp, especially incline is steep but not too long. Therefore, the lovers who use KLX 150 enduro often modify parts of machines, ranging from minor modifications to bore up or even replaced the engine with a Honda Tiger. Yes it seems to have quite a consideration for Kawasaki that many are not satisfied with the KLX 150 engine.
For the use of standards, may not need to be extreme like lah modify bore up the engine. This time Adventuriderz will give tips are easy, inexpensive, and low risk in order to accelerate KLX 150 belonging pal can all be nampol and steady without changing anything in the engine. Yups, way is to change the size of the sprockets or gears.
Replacement of these sprockets can be done with several options, including replacing the rear sprocket with a size larger than the standard size, replacing the front sprocket with a smaller size than the standard size, or even a combination of both. The function of the sprocket replacement is actually to raise the gear ratio. The higher the gear ratio, the acceleration will be better, but the impact on the top speed of the motor is reduced. In addition, if the gear ratio is too high will also make the bike more wasteful of fuel.
More simply, Adventuriderz will give an example with the KLX 150L. In standard conditions, sprocket KLX 150L has a size of 14-47, meaning 14 points for the front sprocket and the rear sprocket 47 for the eye, unlike the KLX 150S uses sprocket size 14-44. Rear sprocket size larger KLX 150L is to adjust the size of tire is greater.
Okee ... Now we start counting. When using standard sprockets, gears KLX 150L has a ratio of 47/14 = 3.357. Well, if Adventuriderz replace the sprocket rear with a size of 50, resulting in the ratio 50/14 = 3.571, if replaced size 52 to a rate of 52/14 = 3.714, if replaced sizes 55 to get the ratio 55/14 = 3.928, or if you want to replace with a size 58 can produce up to 4.142 ratio. It has been very visible right, simply by changing the rear sprocket alone can increase the gear ratio which leads to increased Acceleration bike !!
In addition to replacing the rear sprocket, raising the gear ratio can be done by replacing the front sprocket only with a smaller size. So this is the opposite to the rear sprocket. Examples still KLX 150L with a standard sprocket sizes 14-47. If the front sprocket replaced with size 13 eyes it can produce ratios 47/13 = 3.615, whereas if it is replaced with a size 12 to a rate of 47/12 = 3.916. Buddy also can combine the replacement of the front and rear sprocket. The point is that the ratio rises higher than the standard size.
Suggestions Adventuriderz, easiest and cheapest is to replace the rear sprocket to a larger size. Again keep in mind, drastically raising the gear ratio can indeed improve acceleration, top speed but at the same time significantly cut plus motors are becoming more wasteful of fuel. For daily use of the motor, do not need to wear a sprocket big as size 55 or 58. Guaranteed top speed will ambles. Sizes above 50 may only be suitable for the needs of enduro, not daily. In the case of KLX 150L, suggest Adventuriderz rear sprocket sizes 50-51 only if the motor is still used for daily activities. Rear sprocket size 50 price is also not expensive, only Rp 80,000 only. How its top speed? It certainly reduced sob, but not drastically. If you previously could be 115-120 km / h, after changing the rear sprocket sizes 50 to 100-110 km / hour. Hope can be a reference for all who want to bike buddy more fierce and not oversized when nanjak. Actually it could be applied to the motor what the hell, just stay ngitung ratio.source
