■Details By installing a 5-speed cross transmission, you can accelerate smoothly while keeping the power band of the engine rpm. Also, when SP Takegawa's big bore kit is installed, you can use it without changing the torque-full output performance. This product secures the tooth width by making the travel of each gear a short stroke, and improves durability. It can also be used for stock engines. L.Crankcase cover gasket and R.Crankcase gasket are included in the set.
■Gear Ratio ・Stock Mission 1st:2.500 2nd:1.550 3rd:1.150 4th:0.923
Some people say that it only improves the connection, but what about the effect? Some people say that it only improves the connection, but we wanted to compete with JB-03 (laugh), so we built in the 5-speed! The first gear is slightly lower and the fifth gear is slightly higher than the original Top…. But if the Spec. has increased Torque by Bore up, etc., you can be a little happier if you raise the Front Sprocket by one (lol). There will be more choices of GEAR in the Speed area that is often used, and there will be less GAP between GEARs, which is not without psychological relief. I was worried that the manual might need some fine adjustment. I was worried because the manual says that fine adjustment may be necessary, but in our vehicle, no adjustment is necessary and the feel is not so different from normal gear = originally, the spec. of the footpeg with firmly and lowered footpeg. The most difficult problem may be the labor cost if you ask the shop to install the case.View Detail
I used to have two bikes, a 250cc and a late JC61, but due to various reasons, I gave up the 250cc and became the sole owner of the late JC61. I was reluctant to buy one because it cost 50,000, but now that I have one, and I have 250cc Gold to sell, I took the plunge. I've been an amateur motorcycle maintenance technician for 30 years, but I've never opened a 4th engine before, and I was feeling a little nervous again. In the end, I just removed the engine and sent it to him for installation. I had to wait for a month for delivery, and the engine had to be unloaded twice and sent twice because the flywheel came off. "I don't think this GEAR ratio is right." I had no sense of "This is it!" I am satisfied with the results. The GEAR is a bit sluggish in 4th and 5th gears, but I hope it will become more comfortable as I drive more. It cost me about 100,000 for the kit and installation, but I am satisfied with the condition. The newest model, JC92, is a 5-speed model with Anti-Lock Brake, and I don't think it will be a hardship to change to a 5-speed model, so I think it will be cheaper for new buyers to buy JC92 than to install this kit. However, I already have a JC61 late model, and I like the appearance of the JC61 late model and JC75, so this 100,000 yen investment is not for me personally. Original I am fully satisfied, including the satisfaction of having been able to create the feeling of being able to do so. It's a recommendation to change to a 5-speed for the late JC61 and JC75. And it's a lot cheaper if you can do the work yourself!View Detail
Excellent piece of kit. Always can be in the right rpm range unlike stock transmission. First gear is a little tall, would rather it be shorter but it is still ok. Makes the bike faster and shifting quality is better too. View Detail
Even if you use 4th NORMAL gear, the balance is not good because of the valley of the torque The Grom was very difficult to ride because the fourth gear was too far away, but oh my goodness, what a surprise! A dramatic bifurcation! I was worried about it from a Cost standpoint, but I installed it and was right about the Large I'm having too much fun riding it Is it just me, or do you think it will be a more saleable motorcycle to Honda? With the synergistic effect of the Exhaust System replacement and Power Filter, the I don't feel the Large strange Bore up of Maintenance is necessary The best thing is that a steep gradient can be climbed without stress But it is difficult to feel the difference between 4th and 5th gears because they are too closeView Detail
What made you decide to buy? ◎ The Grom OEM 4 speed Mission shifts into the illusory 5 speed when you are riding Wouldn't it be better to have an OEM or 5 speed Mission? I think, but in terms of Cost... The deciding factor in my purchase was the illusory 5-speed, made real! How was your experience with it? It's a great ride with the feeling that there is another GEAR between the OEM 3rd and 4th gears If I were to give you a Merit-Demerit, Merit is a GEAR-to-GEAR is CROSSing and will accelerate to Smooth Was the installation difficult? It was the first time for me to work on this job The work was done I did some preliminary research on the Net, apart from the accompanying Instruction Manual, and the areas to look out for were I checked it many times 【Please tell me the installation point and hang】 ◎Reconfirmation after the installation of the Mission, Case will be closed with liquid packing, so you can reconfirm it again It's a bit of a hassle to check it again, but it's important to double check before closing, and it's also important to use liquid packing in the gaps between the Small Parts It's important to double-check before closing, and it's also important to make sure the Small Parts are in place with liquid packing through the gaps Be careful not to drop it into the closed Case Also, Clutch must be assembled firmly, otherwise it cannot be cut I failed in building in Clutch and had to worry about it for a week, and then I investigated variously and solved it safely It is important to get the center of the clutch firmly [Was the Instruction Manual easy to understand? ◎ Before assembly, a minimal Instruction Manual is required! I thought it was a good idea, but after I built it in, the point was explained properly, but the 5th speed Since this is a description of the mission, you will need to do some preliminary research on the Others and It's important to read the Instruction Manual as often as you can! [Included Parts:were they on? L.Crankcase Cover Gasket and R.Crankcase gasket are available as a It comes with but Thrust washer 15mm, Bush, ShiftFork ( (Honda OEM Parts) and liquid packing is required, ShiftFork removed You can use OEM parts, but the Thrust washer 15mm and Bush are Removing it from the OEMMission is also a Large odd job It's cheap and can be ordered from We-Big, so you're better off buying it together! [Others] You will need tools and a working kill There are some parts that need to be modified depending on the individual variance, but the assembled 5-speed MissionGROM will be ready to go When I test drove it, it was a lot of fun, something you can't get with OEM Also, after installing the Mission, it's the same as a new car, you'll need to break it in until you get used to each operating part I'm not going to be able to do that I've been doing break-in tours every time I'm on vacation, and I'm planning to change the oil soon It isView Detail
