This short guide will show you the steps to change your sprockets on your Hawk RPS 250 Enduro dirt bike. The sprockets I went with are JT Sprockets 45T and JT Sprockets 17T. You can purchase Hawk 250 Upgrades by clicking here. You will also find other Sprocket sizes depending on your needs.
Step 1. You will need to remove your rear tire and the cover for the front sprocket on top of the gear shiftier. There are 2 bolts holding the cover for the front sprocket.
The next thing I worked on was the rear tire. You will need to remove the 4 bolts holding the sprocket and the clip (red arrow).
It could be a pain to remove the clip if you don’t have the right tools for the job, which is what normally happens to me lol. I was able to get it off but it wasn’t pretty. I’m sure there are needle-nose pliers to make the job easier.
Put the new sprocket on and make sure it sits on straight and then put the nuts on and after that the clip. Check the sprocket after to make sure its not on a angle or misaligned.
Step 3. Once you have removed the cover for the front sprocket, you will need to remove the 2 small bolts and then turn the clip holding the sprocket until it comes off.
Once you have removed the old sprocket, put the new one and put it back together the same way. Rotate the clip until it lines up with the bolt holes and make sure its secured.
With the front sprocket I put on my hawk 250, I had to grid off some of the metal on the cover so it could be put back together. You might be able to put it back without grinding it but a few members have reporting having to grind the edge to clear it.
You can see below where I had to grind some metal off the cover case.
Disclaimer: I have no mechanical experience when it comes to working on motorcycles. Everything I have learned has been from either breaking it and needing to figure it out to get back on the road or watching youtube videos. I’m sure there are better methods to do some of the stuff I’m showing you here but this is how I got it done and it worked for me. Read at your own risk and if there is anything I can help you with, please contact me.
