*Rear sprocket T number / Front sprocket T number = Reduction ratio The higher the value of this deceleration ratio, the more acceleration is emphasized, and the lower the value, the more maximum speed is emphasized. *Changing the reduction ratio will cause errors in the speedometer display, so we recommend using this product in racing.*Depending on the model of vehicle, the number of T's that cannot be installed or the guide plate may need to be replaced or a speed conversion pulse unit may need to be installed.Please refer to the compatibility chart for details.
This is a front side (engine side) sprocket made of S45C (high carbon rope), which is light weight and highly durable. ●The sprocket is a consumable item.Please check the sprocket every 1000km as a general guide.(If the tip of the tooth has become thin, please replace it.The life of the sprocket and chain can be greatly improved by daily lubrication.)
Points of Attention
* If there may be an instruction manual included, it will be written in Japanese.
It is for CBR but it was used for CRF 250L of the same Engine. Rear sprocket 43T It is my purpose to return our Motorcycle to NORMAL, It is cheaper to change Front from 14 to 15 T than to change Rear, It is easy because Chain can be used as it is. The installation went smoothly, but the Gasket made by Gold genre of Sprocket cover interferes. So, I remove Gasket and attach Cover, but there is no particular problem. I think that there are not many people who use these methods, Chains now interfere with Chain Guide. Because I was using Zeta 's Chain Guard Brace, I had some margin.. I am processing the Rubber part of Guide. For those who run, there is no deterioration in fuel consumption at high speed cruising, and the interval between GEARs has become longer I got to be able to run comfortably. Next time I will change the Sprocket cover and I will see it.. View Detail
Because Rear sprocket and Chain were getting worse, I did not wear it, but I thought that I will exchange Front sprocket as well. Buy this item. The cheaper than XAM and SUNSTAR made it the deciding factor of purchase. There is no conspicuous wear etc. after 6000 km, so it's not that it's cheap or bad. Good goods of COSPA.View Detail
Item arrived Melbourne, Australia. within 1 week. Did not have to cut/join chain. just moved rear wheel forward, and 15T sprocket slipped straight on. Took me 30mins and I\'m not a mechanic. Very Happy.View Detail
Bought the 15tooth front drive sprocket for my cbr250r it came from Japan to England in a matter of days and fit perfectly and the quality was excellent. Would highly recommend this company if my experience is anything to go by. Once again THANKS KENView Detail
