LIFAN Expect Front Sprocket Questions
I am looking to replace the front sprocket on my 2020 Lifan 200 X-Pect. 15T to 17T
Reviewing youtube - there seems to be a huge variation from model to model. Some require you break or split chain - some don't. How difficult is it to replace the front sprocket? Do you need to break / split the chain? Thank you. Any words of wisdom / experience appreciated. Jim H ![]() Last edited by goJimH; 11-16-2020 at 09:01 PM. |

No need to break the chain. There are two bolts that hold a retainer. Once the retainer is removed the sprocket and with chain will slide right off. Usually changing the front sprocket doesn't require shortening the chain because there is not much difference in the diameter of the sprocket. Swapping the rear sprocket to a smaller sprocket will require you to shorten the chain.

It really depends on each bike, chain, sprockets, etc. How easily the front sprocket comes off really depends on how loose the chain already is.
You'll probably need to loosen the chain tension to install the 17t sprocket, and you might potentially need to add a link, it just depends on how much slack the chain already has, and how much room you have to slacken it. I would have to disagree with Jerry on one point, countershaft vs. rear sprocket, adding/subtracting teeth on the sprockets, given the same quantity of teeth being changed, will always lead to the same length chain, or the same amount of change needing to be made, for example, both 11/49 and 17/43 can use the same length chain, if installed on the same bike. If you went -2 on the rear sprocket teeth count, you could certainly use the same chain. To wit: +2/-2 is the same effective chain length as -2/+2 in terms of front and rear sprockets. You'll get a higher percentage gearing change from changing the countershaft sprocket, since it's smaller, so it would have a more drastic effect. |

Thank you for your insight....

The simple change I will try to make will be just to the front sprocket. The back sprocket will be left alone. It seems to me - going from 15 teeth to 17 teeth will add approximately 13%. I will report back results. It may be this weekend before I can attempt the switch. Once again - thank you. |

GoJimH, I would like to do the same with my Lifan x-pect, where did you get the 17 tooth sprocket and do you have the part number. I have checked out some sites for a JT 1264-17 and the parts they show differ in the inside spline configuration.

http://chinariders.net/showthread.ph...Lifan+sprocket As I look closer - the sprocket indicated above is JT1264.17 The sprocket I purchased is JTF1264.17 (JTF vs JT) ![]() Only one way to find out. I will be this weekend before I have a chance to look deeper. I will post my results. |

Thanks for Vote of Confidence....

I did not receive a manual with my bike. I am not sure how much it would help - but not having one makes this forum even more valuable. Hopefully I will be able to get a manual soon. |

Front Sprocket Installed on Xpect
Quote:
I installed the front sprocket today and it fits. A couple of cautions / notes: 1. The back wheel was off the ground during installation. That helped. 2. The bolts that hold the sprocket retainer on are soft and will break easily. (Please don't ask me how I know).... 3. Clearance is tight. When replacing the housing cover on - I had to work with it - and - rotate the back tire a little. Luckily I had read about this somewhere else. At first you think it just wont go - but it did. In the pics below - I think my angle makes the clearance look worse than it is. Once again - my thanks to JerryHawk250, Landshark and everyone else who commented here.

You should edit this post and put in a link to your channel.
