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.View Detail

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. View Detail

About quality and texture: I am happy with the quality of this 4V 170cc 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 but the part that makes this big bore kit special is the 4 valve head.About the feeling of use: With the massive increase in the piston size and the addition of valves in the head this big bore kit delivers a huge increase in power and makes the Monkey 125 a beast to ride.Products to buy together: An advanced fuel controller is needed to purchase together with this big bore kit to be able to tune engine once the build is complete. aRacer is a great option but not available here on Webike to suit the Monkey 125.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 4 valve head big bore 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: The big bore kits with the 4 valve heads are more maintenance intensive and require all the supporting modifications to create a reliable engine.View Detail

* About quality and texture, A very inclusive big bore kit here from Endurance. For me the parts that highlight the quality of the big bore kit are the forged aluminium piston, the forged aluminium roller rocker arms and the all aluminium cylinder with ceramic coated paint finish.* About the feeling of use, The peak power that this big bore kit can output is very impressive from what was once a 125cc motorcycle but the power below 6000 rpm is not as impressive as I would have liked.* Products to buy together, Due to the very high rpms this big bore kit can achieve and where you will be riding most of the time to see those high power levels you definitely need to also purchase a reinforced crankshaft from Kitaco.* Difficulty of installation, The installation of the big bore kit requires striping down the complete top end, gapping the rings and replacing the cylinder and head followed by valve adjustments. The process was completed in 120 minutes with a little difficultly.* Cost performance and comparison with other products, When you see the parts list of all that is included and the horsepower this big bore kit can output I consider it good value for money and much cheaper if you are to compare it to the Takegawa 181cc 4V big bore kit.* About shipping and packaging, I am happy to wait 8 weeks on average for my parts to arrive in Sydney Australia via Webike's sea freight which comes with tracking and insurance so I know I'm covered in case something was to go wrong but with there outstanding bubble wrapping and boxing there have been no problems.* Any concerns, cautions, or advice when purchasing, If your riding style leans toward low RPM power then this is not the big bore kit for you and you should research the Kitaco Neo 164cc and 181cc big bore kits. Use the product reviews to assist in making a decision on your purchase.View Detail

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.View Detail
