sounding good
I can't do it myself, so the person who did it for me said that FrontSprocket is very good, in terms of material and lightness, etc. Rear sprocket can be attached with either a pure normal thread screw or a taper bolt, according to the specs. View detail

I was not sure about BlackSteel, but I decided that lightness is justice.
I changed from 43T to 42T, but since it is Rear, I don't think it changes anything experientially.
Next time I will change Front as well and see how it goes.

Change from OEM 14 to 15
The OEMFront sprocket on the GSX250R had 14T and was replaced with a 15T for the purpose of reducing RPM on the highway.
If the Rear Sprocket remains at the OEM tooth count of 46, the speed difference will be about 6-7% if the RPM and selected GEAR are the same.
If high speed touring is the main purpose, the change from 14T to 15T is for Large.
TradeOff is also available, so there is no need to force replacement if you are not currently dissatisfied.
The following are three impressions from the trial run.
・Highway speed range is more comfortable
(RPMs are reduced at the same speed compared to the 14T, and vibration is somewhat suppressed)
Careful GEAR selection at low speeds and on uphill roads.
(Same GEAR, but with the same 14T feelings, it's awkward)
Gear changing on public roads will be slightly less
(less chance of using 6th gear)

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.

I had a hard time removing the OEM.
The product is good, I wanted the Rear brake to work a little better and it worked.
However, there were many places on the YAMAHA chassis where the Torque was higher than the Service Manual, and it was very strange to loosen the Torque here too. I tried to take the wheel to YSP, but I was able to loosen it by warming it up with a burner and buying a proper tool. The screw ruined 1 pc. I wish I had at least used a hex. It was not an easy part to replace at home.

Manufacturer for Peace of Mind
Circuit to change Final
Purchased
Chosen because I wanted to pretend to be Short
Chain slider also needs to be inspected.
It seems to decrease quickly.
It is a secure Brand and I had no problems with the installation.
The first time I removed the OEM's, I had a tremendous amount of difficulty.

Cost-effective
Replaced with SUNSTAR Chain after 15,000 km as the OEM Chain had outgrown it.
The front and rear Sprockets were also replaced with Kawasaki OEM at the same time.
The effect of replacing the Chain, which had been fully extended, is that it is able to transmit power very smoothly.
We recommend this product as it is more cost-effective than other companies' ChainManufacturer products.

Front sprocket15T CB250R
HONDA CB250R's NORMAL is 13T, but we changed it to 15T because we have to turn the Engine on the highway. No modification is required and it can be installed with Bolt On.
No readjustment of the speedometer is required.
With the NORMAL 13, the Meter display showed 88 km/h even at a GPS speed of 80 km/h, which is about 10% higher. However, after replacing the front sprocket with a 15T, the GPS speed and Meter speed are now almost identical.
I expected to see an increase in distance in terms of fuel consumption, but the higher GEAR ratio and higher engine load offset this increase. However, the higher GEAR ratio and higher engine load offset the increase in speed, and fuel consumption was essentially unchanged from the time when the engine was in NORMAL 13.

Controlability
Before the replacement, there was rust on the surface (especially on the back side), and it did not work comfortably when I stepped on it, and there was a strange noise, but after the replacement, the noise disappeared and it works well and is easy to control. View detail

SUNSTAR Front sprocket 525–16T
Prices were about the same as OEMSprocket.
There is a Black color surface treatment that hides it but looks good.
The weight is lighter than the OEM model due to the lack of rubber for running noise control. The installation itself is not too difficult, but when working alone, you need to pay attention to safety by properly securing the motorcycle so that it does not move.
