I purchased a new Sprocket to replace the Chain with a new one.
The price is reasonable and helpful.

Suitable for highways, sluggish in town
The front sprocket does not loosen unless the Impact wrench is turned at the maximum Large Power to install it. From the next time, it can be turned manually.
Also, if you do not take the Bracket on the Cover of the Sprocket, the Cover will not be attached.
The Metropolitan Expressway and the Tomei Expressway are not different.
The start of the road down the road is sluggish and doesn't fit.
(Normally, up to 16T would be good.)
Quantity assuming Fuji Speed way:Set, so will try in April.
On the other hand, we plan to try 14T in Tsukuba and other areas.

It's nice and easy to ride!
I installed it on my WR250R
I have been doing both off-road racing and city driving, so I had an OEM 13 front sprocket, but I decided not to do off-road racing, so I bought a 14T to increase the size to a higher speed.
As for Merit...
No more need for busy SHIFT UP when sending outgoing messages.
Maximum Speed Up
Demerit is
Increased Downshift in traffic jams and on steep uphill slopes.
I think this is about it for Demerit.
As a result, I am happy with the change because I am riding comfortably.

For the final taste after bore up.
I replaced the Sprocket (Front and Rear) while converting to 88cc this time.
Why change Sprocket?
If you Bore up like I did, you will get more Torque and output than 50 OEM.
Therefore, it is necessary to change the OEM Sprocket setting to release the Engine Power more efficiently. If the clothes are too tight, they will tear, right?
So how can we transmit Power efficiently?
GEAR ratio needs to be changed.
The GEAR ratio is the so-called secondary reduction ratio, which is calculated by “Rear Sprocket Ding Number ÷ Front Sprocket Ding Number ”.
In other words, “how many revolutions of the Front sprocket are required to make one revolution of the Rear Sprocket”.
What are the effects or changes that would occur if the Sprocket is changed or replaced?
[FrontSprocket]
● Increase = higher top speed, lower acceleration, lower rpm when cruising, better fuel economy.
● Reduce = no increase in top speed, better acceleration, higher rpm when cruising, and lower fuel economy.
Rear sprocket
Increasing the number of rpm = no increase in maximum speed, better acceleration, higher rpm when cruising, and lower fuel economy.
● Reduce = Increased maximum speed, reduced acceleration, lower rpm when cruising, and better fuel economy.
The effect is reversed for the front and rear Sprocket.
You can replace either the front or rear, but since 1T on the front is equivalent to 3T on the rear, you may be able to save money by replacing the front if you want to change to a larger size.
I use Rear for fine tuning. 。 When the rear is large, it may get caught on bumps,
If the Front is small, the Chain will cut down the Arm, and if it is large, it will hit the Case.
The Front side may be changed by one or two fingers. After that, adjustment is made on the Rear side.
I purchased the CUB for CUB PRESS, which seemed to be expected to be durable, and replaced it this time.
good point
CUB PRESS→ Newspaper delivery. Since it runs with a lot of newspapers loaded, a more durable Sprocket is used than NORMALCUB.
Durability is high.
○Compatibility with ordinary CUBs.
Chose 14 front and 40 rear for balance between acceleration and maximum speed. It is easy to ride.
The front was changed to OEM13→14, which made it easier to handle in first and second gear.
A bad point
○The price is higher than for a regular CUB.
I think it can't be helped because it is made to be durable.
Rotation of the Engine is transmitted from the Front Sprocket through the Chain to the Rear Sprocket to drive the rear wheels. In other words, the above is synonymous with “ How many revolutions of the Engine are required to make one revolution of the rear wheel? 。
In other words, changing the Sprocket's Ding number is a change in the ratio of the Engine's RPM to the RPM of the driven rear wheels. 。
The change of Sprocket is effective not only for bore up, but also for NORMAL vehicles with low speed gear with low torque, such as 1st and 2nd gear, to make it smoother.

Scooter's personality changes so much when you change the pulley.
The acceleration in the start dash, low to mid speed range, and mid to high speed range feels overwhelmingly fast.
Physically, the weight of the Motorcycle has been lightened? I think the weight of the motorcycle has been lightened.
As per Title. changing Pulley makes it a different Scooter.
I can recommend it.

Which is the front?
Purchased for XJR-1300Chainfor Conversion.
I don't know the front and back. installed based on the Line on the body side of the OEMSprocket. I think the thinner side is the body side.

I chose it for its durability.
It was replaced along with the Chain replacement.
The Driven side chose the OEM Product, while the Drive side chose this product for its durability.
There is little difference in appearance from OEM.
The price is probably a little lower.

Rear Sprocket replacement
The Rear of the installed product seemed to be getting a little sharp, so I bought this new one to replace it with a new one along with replacing the Chain with a new one.
The price was not that much, which was helpful.
It looks Black and does not look bad.

It had a good reputation.
[How is it used?
I am playing with Enduro on CRF125F.
I had no particular complaints with NORMALCRF, but I came to purchase this product because all the SEROW and CRF riders around me were wearing this product and raving about it.
Was the installation difficult?
I can't say for sure since I haven't installed it myself, but the person who installed it for me said it wasn't that difficult. If you are not confident, it is better to ask the shop to do it for you.
How was your experience with it?
I was told that the clutch would be sharp, and it was true that the clutch was sharp.
It is also adjustable, so you can enjoy a variety of changes according to your preference and situation.
If you want to add more, I would recommend the Clutch version of the well-reputed Studio Kitamura.
I would like to try it if I get a chance.

Trust Brand
It is easy to install, looks good and Parenthesis is nice.
At 27,000 km on the odometer, the Chain and front and rear Sprocket were replaced at the same time and the improvement was dramatic.
The oil seal on the drive shaft, which was leaking, could also be replaced at the same time, which was very efficient.
Durability is yet to be determined.
