This is a big bore kit that can be used with the stock cylinder head. Increased power and torque due to increased displacement. Especially, the torque is much higher than stock from the middle speed range, and the characteristic is easy to handle.
Points of Attention
* If there may be an instruction manual included, it will be written in Japanese.
About quality and texture, I can confirm that the quality is great and that the materials used are a combination of aluminum and cast iron for the cylinder, aluminum for the piston and steel for the piston rings. About the feeling of use, This much larger then original 181cc displacement cylinder and piston kit creates a huge amount of torque for some fun riding experiences. Products to buy together, An oil cooler is a necessary product to buy right away to keep the higher compression piston from overheating and maximise the kits life. Difficulty of installation, I can say the fitment of the big bore kit and for my installation was easy due to having performed this type of job a few times now but if it is your first time it may be difficult due to understanding what needs to be done and all the tools involved, you may want to consult a mechanic. Cost performance and comparison with other products, The pricing of the product is the best. You receive well manufactured and designed parts for the JB02 and JC61 models made from a high quality material and much cheaper priced then the equivalent kit made for the JB03 and JC92 models. About shipping and packaging, My order was shipped within 24 hours of the product being in stock and I received a few emails advising me of the status up until the order was dispatched. The order arrived within the estimated date range and was extremely well packaged. I found the link supplied to track my order very useful while I was waiting for the order to land in the country. Any concerns, cautions, or advice when purchasing, I have no concerns or cautions when purchasing from Webike. I cannot recommend Webike enough for the majority of your biking needs. They not only sell aftermarket parts and bike gear but also OEM parts for your repairs and servicing needs.View Detail
