About quality and texture: I am happy with the quality of this crankshaft kit, the crankshaft is reinforced and the forged connecting rod is designed for maximum strength while remaining light in weight. This being the higher priced of the 2 products available from Takegawa it also includes their crankcase gaskets, woodruff keys and a cam chain.About the feeling of use: With this crankshaft kit now installed I can ride my modified Monkey with enjoyment and without the constant dread and wonder of if the crankshaft is going to break today.Products to buy together: The TAF 5 speed cross transmission kit from Takegawa would also be desirable to purchase along side their crankshaft kit as the access is there to now easily install this and it will also complement your big bore kit.Difficulty of installation: I had the local Honda motorcycle shop install the crankshaft into the right crankcase for me as I did not have the required tooling. The process to install takes about half an hour. Not difficult to do if you have the right tooling.Cost performance and comparison with other products: Good costing as you are getting a full crankshaft kit with all the additional parts to complete the install without having to re-use any of the Honda parts as compared to crankshaft available from Kitaco which is cheaper but gives you nothing but the crankshaft.About shipping and packaging: The faster shipping options are too expensive for myself so I just have to wait for my part to arrive via sea freight. Webike kept me updated on the status of my order up to when it shipped. The parcel arrived within the expected date range and was well packaged with no chance of the part being damaged.Any concerns, cautions, or advice when purchasing: If you are purchasing a big bore kit and are thinking you can get away without also purchasing a crankshaft from either Takegawa or Kitaco, I can advise that you may get away with it for a while but eventually it will fail and end up costing you more money in the long run.View Detail
After i installed the takegawa 181 4v big bore kit, i broke my stock crank. The stock crank just cannot handle the power. This crank will allow you to rev your engine to 11000 rpm. The build quality is fanstastic.View Detail
