【DRIVEN】Front sprocket Review

Outstanding Effectiveness! Gicky resolution!

[How is it used?
I was uncomfortable with the jittery feeling when driving at slow speeds, such as in traffic jams, so I wondered if the jitteriness could be eliminated by setting the secondary deceleration to Long. I decided to replace the system in the hope that the jittery feeling would be eliminated by setting the secondary deceleration to Long.

Was the one you received as per Image?
This is a Race ish Sprocket that has been machined with holes to reduce weight.

Was the installation difficult?
The Bolt that holds the Sprocket in place does not require an Impact Driver to remove it. It is held in place by two regular 6mm bolts, which can be worked with a ratchet wrench. The OEM Chain LINK number is 112, but if it is a combination of 16T and 42T, even 110 will be enough. The OEM chain has 112 links, but the combination of 16T and 42T seems to be sturdy even with 110 links.

How was your experience with it?
Since the front was set to 16T and the rear to 42T (OEM was 15T and 45T), the reduction ratio changed from 3.00 of OEM to 2.625, which is a much longer setting. I was worried that the low-speed Torque would weaken when starting from Zero, but this was not the case at all! It is so easy to drive without any stress. As a by-product, the fuel consumption has been remarkably increased to around 35 km/liter, which is a very good thing in these days of high gasoline prices! The Rear Sprocket is a JTSprocket part number JTR890.42ZBK. Unfortunately, this Sprocket is not available at Webig.

[Included Parts:were they on?
Nothing.

[Was there anything that disappointed you?
If I had to say something, it would be the price. A typical Japanese-made product can be bought for around 3,000 yen. (This product is made in the U.K.). View detail

This was the only 14T available.

I installed it on a 2011 CBR1000RR.
I was a little worried because it was made by Driven, a manufacturer I was not familiar with, but I was able to install and use it without any problem at all. I recommend this product to those who are looking for a niche size. View detail

sufficient for one's needs

Durability is unknown as it was just replaced.
Parts that are fine if there are no defects.
We lowered it one notch from the model standard value and set it at 16. This is working as expected, as we are able to reduce the number of half-crakes during startup and low-speed driving. View detail

It can be diverted without any problem.

This is a diversion to DF200 DJEBEL.
The standard FrontSprocket of the DF200 DJEBEL is 15T, but
Driving at 80 km/h cruise, the Engine RPMs will be higher and
Stress was felt.
So I looked for one up 16T, but there was no setting.
Only ZAM was Released for SX200.
DJEBEL is the successor to DJEBEL, so it has not been confirmed as compatible. "Maybe it will stick." I decided to purchase the product, but had to give up because of the undecided delivery date.
I found this product when I was in this situation, and although the DF200 DJEBEL was not compatible. "Maybe it will stick." and decided to buy it.
The results were diverted without any problems.

The DF125 DJEBEL can be used with no problem by converting the rear sprocket to DF200 DJEBEL and the chain to 520 size. View detail

Used for RVF400

Used for RVF400. I looked for a lot of things and this was the only one I could find. View detail
