I chose SUNSTAR after Chain replacement work of CBR 250 RR. The difference between the other companies' products is precision! Because other companies have slightly out-of-round circles, only loads not required for the car body are applied. I think that you should choose SUNSTAR if you want to replace it.
【What made you decide the purchase?】
? Since I chose MADE IN SUNSTAR 's Sprocket to exchange Front sprocket, Rear also decided on the same MADE IN SUNSTAR. At that time, because Smront reduced the number of teeth of Front, adjust the secondary reduction ratio by decreasing Rear also Small
【How was it actually used?】
? Material : It was sometimes converted to 520 in Aluminum, which was lighter than 500 g more than Steel's STDSprocket. Thanks to that, the falling down of the car faster but, of course, not by the effect of Rear Sprocket Single Body, but by the Balance of Sprocket and Chain
? Assuming that Response will be too good by converting, we aimed at offsetting the secondary speed reduction ratio slightly to Long. As a result, it settles to Response of about + α before change
【Mounting was difficult?】
Although both Axle Shaft and Sprocket are tightened by high Torque, there is no point that it can not be disengaged like Front sprocket, so if you can remove RearThailand, exchange is comparatively easy. Chain adjustment after installation is more difficult
【Please tell me the installation point and hang】
? Sprocket's Nut can turn Nut more consistently and easier to take force than before unfastening after removing Wheel
? To remove Tire, hold down Caliper support and remove. Caliper support falls and hurt Wheel
[Is there anything I was disappointed about?]
? Anodized began to peel off slightly when traveling slightly less than 100 km. I predicted that aggressiveness to Sprocket will increase as I dropped it to 520 Size, but it seems I expected too little
【Hope for Manufacturer ? Please let me know if there are any improvement points]
? `MODEL after 15 years Steel's Sprocket was released, but since there is not yet MODEL before that, please do also here
【Have you compared items?】
? DRIVEN : Rear Sprocket
? Hub damper is also a consumable item, so please check the downs and exchange
As for installation, accuracy is high and there is nothing wrong with anything. Because it is MADE IN SUNSTAR it is not worrying about it.
And it looks good as saying Aluminum Sprocket! It is a golden golden ★
One thing to worry about is durability by saying Aluminum. It is still in use and details are unknown, but in particular OffRoad rider needs attention. Off If you are using SUNSTAR Stenz is recommended.
