Front and Rear Set Replacement
DID and Quantity:Exchange in Set
Rear selected 42 pieces, one more than the OEM, ordered separately from the official
The replacement was easier than I expected.
The Torque is slightly higher than before, and it feels good.

Functional beauty!
I replaced the ISADriven Sprocket with the Driven Sprocket as a press-up, and I could feel the direct response to the throttle operation. As a conclusion, the Driven Sprocket was not able to feel the goodness at all when riding after the replacement. However, I am satisfied with the beauty of the machining and the high quality of the parts themselves. By the way, for wr250x, there is no hole for weight reduction, but the reverse side was cut out by cutting. View detail

Sprocket is an ISA
My Motocrosser FSprocket teeth were bent, so I replaced them front and rear together. I used ISA for both front and rear.
The meshing with the Spline on the Output Shaft was also perfect.
It was too snug and I had to tap it in lightly. There was no rattle at all.

Sprocket is ISA!
I bought the ISA Sprocket for my Off-road motorcycle because the one that came with the OEM was diminishing. I've tried other manufacturers' sprockets in the past, but ISA's sprocket never wears out! It lasts a long time. The balance of lightness and price is perfect. View detail

I'm not ready to...?
FrontSprocket OEM13 to 12 on WR250F. Purchased.
But, however, the Shift change and Accelerator operation are It can be severe and surprisingly difficult (sweat)
I think I'll get used to OEM first, and then I'll be able to replace it. (I thought it would be good to use differently for different courses.

I'm sorry
I bought it to change the Ratio but I haven't used it, sorry
And it seems to be a Made-to-Order or generally not in stock
I bought it because I wasn't comfortable driving in first gear through a mountain pass, but now I'm used to the sledding I haven't found it to be inconvenient without replacing it
I'm sure I'll replace it at some point, but if it's going to be a 520Conversion in the future, it's really going to be in storage Maybe..

Sprocket is decided by this!
High mounting accuracy and Length of lifetime are very good.
It seems that you can still use it as much as 5,000?.
Initial investment may be high, but lifetime is long
Lightweight mounting is careful because of its high part precision

The hole without meat is opening Sprockets of inside with many products which do not have an Impact in appearance, and ISA, such as a Sprocket of
AFAM, and the engine performance after exchange is a product it can be satisfied also with appearance of a product from a dimension.
Brando also has sense of reliability and is a Recommendation.
