Low.
[How is it used?
I am enjoying playing in the mountains with CRF125F. It is a great machine with no complaints at all, but there is one point that bothers me when I play with it. It is that the first gear is too low and the second gear is too far away from the first gear. I thought it would be better if I could use the 2nd gear a little more. So I bought this product.
Was the one you received as per Image?
I received a product that was probably some kind of OEM Parts Repack. I think I can find out if I look into it, but considering the time it takes to look into it, it would be quicker to buy this product from Rikizo. Gold is the solution.
How was your experience with it?
Dropping one Front works pretty well. It has changed more than I expected.
I can now drive at speeds where I feel like I'm stalling in 2nd gear without having to drop down to 1st.
[Included Parts:were they on?
Fixing plate and mounting Bolt are Standard Equipment. Gentle.

Secondary reduction ratio to Long side
Tuning was easily accomplished by simply changing the Driven Sprocket from a NORMAL secondary reduction ratio of 2.5 to 2.3.
The NORMAL has a pleasantly thick Torque feel, but I am a little dissatisfied with the handling of the first and second gears after tuning,
The low level of the car is easy to maneuver, and smooth gear changes can be made from startup, increasing the sense of speed.

A good option
The front sprocket was changed from 14T to 15T keeping the rear sprocket the same. No modification needed at all. This is a slot-in replacement. The sprocket makes the power delivery in 1st and 2nd linear. There is pronounced knocking in 2nd gear at 30kmph. This wasn't there before but need to get used to it. Very good performance in 3rd and 4th gears. Easier to go above 100kmph in 4th and maintain speed. This modification doesn't impact the overall performance of the bike in city traffic. I live in Bengaluru and traffic here is at a different level. Recommended for people who tour often on the bike. View detail

Perfect for off-road
I replaced it because I do a lot of off-road driving.
The 13T Driven Sprocket makes touring a little more difficult, but I am satisfied with it for off-road use.
Not recommended for On roadTouring Maine.

![520 Chain Size Convert Series [Front Sprocket]](https://global.webike-cdn.net/photo/impression/62/627da0add52ed2a45bc055376e243bd3L.jpg)

Made by XAM.
I bought this to convert the chain size of my SEROW250 from 428 to 520.
I wanted the secondary reduction ratio to be as close to the OEM 3.2 as possible, but I decided to go with the 12, which is almost the same size as the OEM, because the 11 would hit the chain slider harder and there would be fewer options for the rear sprocket.
For 12 guns, the OEM approximation is 3.17 for a 38 Rear Sprocket and 3.25 for a 39 Rear Sprocket reduction ratio.
I set the Rear Sprocket to 38, and the Chain Link number to 106, but the Chain Adjuster is at the back, near 13.
The length of the chain can be calculated by Pitch×LINK number, but it was easier to use DID's Chain link calculation table.

I bought it in a longer LINK number just in case and Cut it.
I've only used it for about 10,000km now, so durability is still unknown, but it will probably outlive the Chain.
