So much more fun to ride

About quality and texture - The 170cc 2-Valve cylinder kit from Endurance is made from cast and forged aluminium, the quality from the overall fit and finish is perfect.About the feeling of use - The larger 170cc displacement cylinder and piston even when combined with the rest of the original 2-valve setup is so much more fun to ride.Products to buy together - The key product to buy together with the 170cc 2-Valve cylinder kit is the X-Beam connecting rod crankshaft from SP Takegawa. This kit when added to the original crankshaft increases the chances of failure but this can be lower when the X-Beam connecting rod crankshaft is installed.Difficulty of installation - The installation of the 170cc 2-Valve cylinder kit is an advanced task that took 1.0 of hour to complete, so much more fun to ride. due to the preparation and alignment of the piston rings. Mechanical aptitude and the use of basic hand tools is what is required to secure piston to the crankshaft and fit in the cylinder.Cost performance and comparison with other products - I find the cost of all the products Endurancea sell to be on great value when compared to what most other companies sell their products and this is also the case with the 170cc 2-Valve cylinder kitAbout shipping and packaging - With there being a significant cost difference between sea freight and EMS for the 170cc 2-Valve cylinder kit, I chose sea freight for a cost saving. The part was extremely well protected while being covered in bubble wrap and surrounded with air pillows in a sturdy cardboard box.Any concerns, cautions, or advice when purchasing - Webike Japan is the first place I look to for all my motorcycle needs. From service parts to performance products and even motorcycle gear and apparel, Webike always seem to satisfy my needs in regards to availability and pricing.

A cheap option to give you a good amount of bottom end power

About quality and texture, I can confirm that the quality is great and that the material used is mostly aluminum in this kit. About the feeling of use, A cheap option to give you a good amount of bottom end power produced for an everyday ride from the larger 169cc displacement piston. Products to buy together, A fuel controller is a necessary product to buy right away and a freer flowing exhaust would be ideal to add to your cart. Difficulty of installation, I can say the fitment of the big bore kit 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 of 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 great. You receive well manufactured and designed parts for the JB02 and JA48 models made from a high quality material with equivalent kit made from other brands being much higher priced. 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.

By Far the Best Bang for Buck BBK for the Monkey 125

About quality and texture: I am happy with the quality of this 169cc big bore kit. The cylinder is all aluminium without a steel sleeve and the piston is aluminium but forged and not cast like the cheaper kits would tend to include.About the feeling of use: With the massive increase in engine capacity, the power in the lower RPM's is fantastic and top speed can be achieved much quicker.Products to buy together: A performance camshaft would also be desirable to purchase along side this big bore kit as one is not included, this will help to continue producing more power in the higher RPM's.Difficulty of installation: The process to install takes about two hours and that includes checking all the ring gaps and adjusting before assembly. A little difficult to do but the Honda service manual has all the information to help you get the job done.Cost performance and comparison with other products: Great costing as you are getting the best bang for buck BBK kit out there and the quality is outstanding as compared to the much more expensive Takegawa kit that is slightly larger in capacity but does use a cast aluminium piston.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 also looking to purchase a camshaft and fuel controller at the same time as this big bore kit then don't buy just this big bore kit but the complete kit containing all the above which is available here on Webike too for a much better price then purchasing the items seperately.

ENDURANCE Hi-Power Big Bore Kit for Honda Monkey 125

About quality and texture - Top quality. For the lower price of this kit I am really impressed with the forged piston and ceramic coating on the cylinder.About the feeling of use - Looking forward to having more torque down lower from the 170cc kit.Products to buy together - To run this kit reliably you are going to need quite a few additions but an oil cooler will be very important to keep those engine temperature down.Difficulty of installation - Doing a top end rebuild on these engines from Honda is not too difficult at all. Do yourself a favour and research before pulling things apart and you should be able to complete the job in an hour.Cost performance and comparison with other products - The cheapest big bore kit I have found available for the Grom/Monkey and with quality parts that rival the other brands.About shipping and packaging - I think Webike are doing their best with shipping pricing, so I'm happy. Packages ship within 24 hours and arrive very quickly from JapanAny concerns, cautions, or advice when purchasing - Don't think you can just bolt this kit on and ride. Do your research and learn what other parts you will also be needing to purchase from Webike to build yourself a reliable upgrade engine.
