【What made you decide the purchase?】
? I thought about changing the Chain variously, but I will buy it as a DID made Chain which is also using Yamaha FACTORY. As long as you buy it, I was also interested in Conversion from 530 Size to 520 Size, so I decided to change the width of Chain
【How was it actually used?】
? Since I made 2SizeSmall out of 530 Size, pushing pulls and falling down of the car got lighter, but there was no radical change like rumored. Grease adhering to Chain from the beginning is resistance if it does not wipe it, it is better to drop early as it can not demonstrate its original performance
? After exchanging Chain I avoid running behaviors suddenly due to break-in, I ran about 70 km and looked at the initial elongation, the elongation of about 5 mm could be confirmed. After that, the initial elongation when traveling 300 km at Total remains unchanged 5 mm
【Mounting was difficult?】
? I used a company's Chain Cut & Crimp tool to do a series of work from Chain's Cut to Crimp, but I was able to exchange it without problems for the first time. Just in case of R1, due to the shape of Swing Arm, I can not work unless Rear Fender is removed and the upper Chain is not done
【Please tell me the installation point and hang】
? Since converting to 520 Size caused the width of Chain to be narrowed, we exchanged the Sprocket first and then pulled out the new and old Chain so that the teeth mesh with each other
? Since Plate crimping and Crimp are the essential parts, there is no failure when measuring while measuring with the neighboring Piece every time of work
[Is there anything I was disappointed about?]
? Although the high rigidity Chain of the Flagship model seems to have weight as much as Long life, it is not light as unexpected as 1930 g even at 118 L of 520 Size
【Hope for Manufacturer ? Please let me know if there are any improvement points]
? I changed the 420 Size Non-seal Chain, but for the first time exchanging the Seal chain this time I was surprised by the amount of Grease attached. Although it is a purpose of rust prevention, if you reduce the amount a little more ...
