About quality and texture, I can confirm that the quality is great and that the materials used are a mixture of aluminum that is CNC machined to shape and finished with an all black anodized finish and steel ball bearings. About the feeling of use, Superbly assembled kit that aids in the longevity of the 3Gen Grom engines crankshaft. Products to buy together, Other parts to help improve the reliability of the Honda 125cc horizontal engine like the Takegawa cam chain tensioner would be ideal to add to your cart. Difficulty of installation, I can say the fitment of the crankshaft support adapter for my installation was average due to the amount of access required to get to the internals of the engine and the special tools needed to complete the installation. Cost performance and comparison with other products, The pricing of the product is good. You receive high quality material and well designed parts, cheaper options are available from Thailand vendors. 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
