August 18, 201214 yr Hi All New starter with second hand bike! I am planning on changing my Rear sprocket to a red one to follow on with the colour of my bike. I do not have my rear wheel at the moment so I can not count the teeth. What is the standard set up for the amount of teeth on the front & rear sprockets please ( how many on each sprocket) & what would be the benefit to change the teeth pattern?
August 23, 201214 yr You don't say whether it is 2t or 4t or what capacity, so assuming it is a 2 stroke 250, 290 or 300, the front sprocket would be 11 teeth and the rear 41. If it is a 200, it would be 11,42. The sprocket size is chosen to get the best performance in all gears, some people do change, but I'd stick with standard until you get used to it!
August 23, 201214 yr We bought a fancy S3 sprocket and changed the tooth size. Stayed on for 1 trial the standard size was best all round .
August 23, 201214 yr Author Sorry its a 2T & 250 cc, so 11 front & 41 rear it is then. thanks for the help chaps.
August 24, 201214 yr I can't remember where I got this from but I heard " you should never have an odd number front and odd number rear sprocket or both ends even numbered. They need to be odd and even on the same bike. You need to have an odd front and even rear or vice versa. This helps how the chain meshes with the sprockets". I have no idea where it's from or if it is true. Could be worth a Google though?
August 24, 201214 yr Ah that's called hunting tooth i think. Used on bevels and meshing gears to ease the wear on them but not heard of it on bike sprockets?
August 26, 201214 yr That's good then. I have no idea where I got it from but when I saw the post it made me remember it. Seems daft being concerned about wear when you generally have a chain covered in mud, sand and grit!
