엔즐을 바꾼다구 해도
<br>
기러케 소음에 큰 차이가 없는걸루 알구 있슴다...
<br>
글구, 기본 차체엔진이 아닌,
<br>
다른엔진을 얻으면 불법튜닝이 되는건데...
<br>
정품이 아닌 셈 이져..
<br>
기러므로 A/S점검시에 상당한 불편을 겪으실수 있을껌다...
<br>
아니, A/S가 안되는걸루 알구 있슴다...
<br>
기럼, 부품을 사다가 혼자 고치구 조이구 해야할텐데
<br>
좀 시끄럽더라도 기냥 타는게 나을듯 싶네여...
<br>
혼자서 고치구 조이구 하는것보다는...쩝~~/

Honda Releases the UMK425 --- The World's Lightest 4-stroke Trimmer
<br>
<br>
Tokyo, April 22, 2002 --- Honda Motor Co., Ltd. today announced the release of the new UMK425, the world's lightest*1 4-stroke trimmer, equipped with the 360º -inclinable GX25 4-stroke engine. The UMK425 is expected go on sale early in the second half of this year at Honda power equipment dealers throughout Japan. (The UT Type goes on sale August 6th.)
<br>
<br>
Developed in accordance with the concept, "lightweight, light start, light touch," the UMK425 is designed to be the lightest 4-stroke trimmer in the world, delivering both high cutting performance and ease of use.
<br>
<br>
Thanks to the GX25 engine (the world's lightest 4-stroke), compact gear case, and unitized fan cover made of a special plastic that is both lightweight and vibration-resistant, the dry weight has been reduced to just 4.8kg --- on a par with 2-stroke trimmers. Further innovations include an optimized drive gear, specially designed compact and lightweight gear case, and weight distribution optimized for maximum operability. In addition, decreased vibration and lower mechanical noise result in a trimmer that significantly reduces operator fatigue.
<br>
<br>
The GX25 also offers superb environmental performance, achieving a top-class*2 ranking under American EPA (Environmental Protection Agency) Phase 2 regulations --- the most stringent in the world.
<br>
<br>
*1 As of April, 2002. Dry-weight measurement, cutting head not installed.
<br>
*2 EPA: Class I-A (under 65cc displacement) and Class IV (20cc~50cc displacement)
<br>
<br>
Another model of the same trimmer, the UMK425H, is expected go on sale early in the second half of this year at designated home centers. This model is equipped with a body designed to home center-series specifications. (The UT Type goes on sale August 6th.)

Other Features of the UMK425
<br>
<br>
"Fine Start", for smooth startup and superb acceleration
<br>
Mechanical decompression results in a class-beating starter rope pull weight of just 7kgf (Honda in-house testing) --- so light that anyone can start it with ease.
<br>
A newly developed accelerator pump-equipped carburetor results in excellent acceleration immediately after startup, comparable to that of a 2-stroke.
<br>
<br>
Nimble operation Weight distribution is optimized for maximum operability. The "Fine Frame" results in a significantly lower shaft swing moment, for reduced operator fatigue.
<br>
The "Fine Grip" features a slimmer handle shape that is easier to grip for people with small hands.
<br>
The "Fine Throttle" employed on the U Type combines the engine speed-adjustment lever with the throttle fixing lever --- just squeeze to fix throttle speed. This results in reduced operator fatigue, even when operating the trimmer for an extended period.
<br>
The "Fine Trigger" employed on the UT and L Types combines a lever that is easy on the fingers even during extended operation with one that allows immediate engine speed adjustment.
<br>
The piston and other moving parts have been lightened for reduced vibration, resulting in less fatigue during hand-held operation.
<br>
<br>
Environmental performance The Honda e-SPEC engine achieves top-class* ranking in both American EPA (Environmental Protection Agency) Phase 2 regulations and CARB (California Air Resources Board) Tier II regulations --- the most stringent in the world.
<br>
*EPA: Class 1-A; CARB: Under 65cc
<br>
Achieves top-of-class fuel economy and oil consumption.
<br>
Oil-immersed timing belt reduces mechanical noise.
<br>
<br>
Design The unified pipe frame and engine and full-cover construction reduce snagging on branches or other objects during operation.
<br>
New Power Red coloring heightens brand identity for Honda power products.
