This S stage 181cc bore up kit from Special Parts Takegawa is a great complete kit for a top end rebuild that results in a nice torque increase. The kit comes with everything you need and helpful instructions once you translate them for a successful installation. Webike does offer many kits like this from other companies and some maybe cheaper to purchase but I chose Special Parts Takegawa as I have had great experiences with their other products I have used on my Honda Monkey 125. If you have questions about parts from Special Parts Takegawa do not bother asking them directly as they never responded to me, just ask Webike as they never fail to respond due to their great customer service.
About quality and texture: I am happy with the quality of the 181cc big bore kit from SP Takegawa. The cylinder is all aluminium with a ceramic painted finish and the piston is cast from aluminium.About the feeling of use: With the large increase in engine capacity and also increase in compression, the power in the lower RPM's is outstanding and higher top speed can be achieved with a change in gearing.Products to buy together: The sports camshaft from SP Takegawa would also be desirable to purchase along side the 181cc 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 with no adjustment required before assembly. A little difficult to do but the Honda service manual has all the information to help you get the job done correctly.Cost performance and comparison with other products: Good costing as you are getting a high quality big bore kit with the large 181cc capacity that smashes the competitors. Not the cheapest kit avalable but still great value from one of the best companies.About shipping and packaging: Sea frieght was my perferred method of shipping due to the lower cost but currently unavailable due to Japan Post. 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 looking for a simple tuning option then the SP Takegawa FI-Con is what you want and if you are looking for the best tuning option then the aRacer Mini-X and AF2 is what you want but not currectly available from Webike.View Detail
High quality kit that is a huge increase in performance from a DHM stage 3. Install was easy. Wish I would have gone big bore from the beginning instead of trying a high comp piston.View Detail
About quality and texture - Top quality. I am very satisfied with the quality of the kit and the finishes on the ceramic coated cylinder and cast piston.About the feeling of use - After the initial install I was still using the OEM camshaft and was also very satisfied with the large torque increase in the low to mid RPM range as this is where I do most of my riding.Products to buy together - A camshaft is a great item to upgrade along with this bore increase. Webike have many to choose from and they vary wildly in pricing, it would be nice if there was some reviews by one person on all that is availble so we could make a better educated decision on which to choose.Difficulty of installation - I found this installation process challenging as this was my first top end upgrade but if you do your homework and have the correct tooling the job is of an average difficultly.Cost performance and comparison with other products - Since the Kitaco 181cc kits are no longer on offer here for the Monkey 125, this Takegawa kit is the only 181cc available but if you are happy to go slightly smaller Endurance offer a 170cc kit for almost half of this price.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 Japan.Any concerns, cautions, or advice when purchasing - Take into consideration the piston from Takegawa is cast and the piston in the 170cc Endurance kit is forged, if that is something you would prefer.View Detail
Top Quality parts, but most of all well engineered to create a cohesive outcome, there are many options out there but this piston from Takegawa maintains a great combustion chamber shape with the stock head, and includes a relief for the spark plug (so no spark plug spacer required). The result is a engine that runs as good as OEM Honda but has just a bit more go everywhere. In my specific kit the piston rings were mostly ok to go out of the box, If I was being picky I'd say the top ring was a tiny bit tight and the second ring was a tiny bit loose, the oil rings were perfect. As a result I opened up the top ring from 0.009" to 0.01" only becuase its going into a CT125 which naturally runs hot vs GROM/Monkey. But I think I could have run the rings out of the box and probably had zero issues. I also like that the piston is 4 grams lighter than the stock piston, this means the motor runs very smooth with little vibration. The N-15 cam is perfect for a OEM plus feeling, I've tried a range more agressive cams and the bottom end always suffers, in my opinion that does not suit the charater of the CT125 however, this N-15 cam is perfect for the CT125 imo. I like this kit so much I'm considering buying a second to keep in stock as nothing lasts forever. View Detail
Quality of the product is exceptional. Fitment is excellent and everything goes together without any problems. All parts included are constructed or machined to very high standards visually. Structurally the parts appear to be designed the same as or better quality than oem. Power output from installation of this kit is significantly better than oem. View Detail
About quality and texture, I can confirm that the quality is great and that the materials used is a combination of aluminum and steel in the kit. About the feeling of use, This combination of the larger 143cc displacement piston and higher RPM range cam gives you the perfect amount of power for urban riding with the need for less supporting modifications then the 181cc kit. Products to buy together, A fuel controller is a necessary product to buy right away and a freeer flowing exhaust would be ideal to add to your cart to maximize performance. Difficulty of installation, I can say the fitment of the big bore kit and cam 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 great. 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 JC93 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

I'm fine-tuning my Monkey. To increase the engine power, this kit was purchased. How wonderful everything is done! I really like both the quality of the material and the precision of the workmanship, even outwardly everything looks very wonderful. Well, the most important thing is that I got an excellent power reserve, the speed increased significantly. Definitely recommend...View Detail
Really nice stainless steel exhaust system from Special Parts Takegawa at a great price here on Webike. If you are looking to get rid of the quite Honda OEM exhaust system but still wish to retain the factory look of your Honda Monkey then this is the exhaust system for you. This exhaust gives the little 50cc engine a nice note that you can now hear. Fit and finish of the exhaust is very nice and I do like the fact that if required in the future repacking of the muffler is made simple by the the use of rivets in the end cap. Comes with everything you need for a successful installation.View Detail
I was in the market for a new air filter for the Monkey and decided to give this one from Special Parts Takegawa a try. I have not purchased a part from Special Parts Takegawa that I did not like and this part is no different, it gives that nice intake noise and just looks trick sticking out the side of the frame like that. I will say that I would like to add the water resistant cover that they also sell to suit their pod style air filter. Comes with a breather attachment so you do not need to run an additional breather filter which will save you a few dollars.View Detail

When I picked up this Monkey the Honda OEM rear shock had no life left in them and I did not even waste anytime looking at other brands just went with these rear shocks from Special Parts Takegawa as they are my go to brand for the Monkey and have not disapponited this time either. Simple installation that anyone can do with the basic tools in your garage and I would suggest also remembering to add a little grease to the mounting posts to keep that area rust free. Nice OEM looking rear shocks with a spring rating that is more suitable for an average sized person. View Detail

I really love this part from Special Parts Takegawa, it just makes the Monkey look a million dollars and gives the engine overall just a better feeling. This special clutch kit also now gives you the ability to have a real oil filter and if you are going to run an oil cooler also the ability to have it start cooling when required by adding a thermostat. Such great thought has gone into designing this part. Installation skill required is medium and you will be needing some special tools which Webike has on offer. Expensive but well worth it.

After some researching into all the different kits available for the Honda Monkey here on Webike I decided to go with this particular kit from Special Parts Takegawa mainly because it tucked nicely out of the way under the luggage rack with the up style exhaust and had the correct breather fitting to work with the clutch cover I have fitted to the engine. Do yourself a favour and also buy some hose a cutter from Webike too so you can have a perfect finish once the installation is complete. An expensive kit but it comes with everything you need and you don not have to spend a dollar more.View Detail
