Rear Sprocket on Templar X
Hello! I am new here and purchased a Templar X in April. Have really enjoyed it so far and made a few mods, with the help of this site.
![]() I am in the process of swapping out the tires for some 50/50 Kenda K270's. While changing out the rear tire I want to swap the rear sprocket to bring down the RPM's some while tooling around on the black top. I purchases both a 45 and 42 tooth JT rear sprocket. My question is, will I need to get a shorter chain or remove a link if I go to the 42 tooth? I ask as the rear tensioner is already about 3/4 toward the rear, so wondering if I will run out of room to adjust & properly tension the chain. |

Yes, you will need to shorten the chain. If you have a dremel or grinder, it's an easy process.

All you need to do is remove a link or two. Get a chain break (~$15).
You will need one in the future anyway when you buy a new chain and need to remove some links, or when your chain stretcghes and it is too long. This is a basic motorcycle tool to have when you own a motorcycle. It will get used.

Took two links out of my stock Templar X's chain with an angle grinder, straight punch, and 20t shop press.
Mostly because I needed it done that day and couldn't be bothered going over to my Dad's place to get my breaker back.

Thanks all! I will get to work removing the chain and start taking some links out. Anyone recall how many links they had to remove on their stock chain to fit the 42 tooth? Would love to get it right the first time, if I can.

You will have to adjust to about 65-75% forward on the axel slot, square on both sides. This is so that you can loosen if needed, or tighten the chain after removing the links.
Then pull the chain around the rear sprocket. Determine the overlap, estimating appropriate slack in the chain... Look closely, because removing "one" link is actually removing two sections. They have to go back together using the master link. No one can really be certain about the number of links you need to remove.

You can use a chain breaker, to reinsert the rod in the chain and close the loop.
I've done several thousands of miles on an OEM chain which I've shortened this method. |

I usually remove the chain and hang it for lubrication. It is so much quicker and easier with the master link. Personally, I trust it more than reinstalling with the chain break. Always install the open side of the master link clip on the trailing side, make sure the link and chain are clean during install.

I've had one master link come apart/disappear. An older and well worn enduro bike I bought a few years ago had two spare master links hooked on the clutch cable. I figure there was a reason the previous owner wanted those handy. So I expect experiences vary.

Thought I would report back on my findings & outcome. I used the process that Thumper outlined and it worked perfectly. Ended up removing a total of 2 links to get the 42T sprocket with the stock chain to fit and adjusted correctly.
The higher gearing is exactly what I was needing and the 42T was the correct way to go. Thanks again for the assistance. |

I have a lot of chain slap noise with the smaller sprocket. I wonder if the small rear sprocket just puts the chain too close to the chain guide on top of the swingarm?

yeah, I'm running 13/40 on mine and notice a little more noise myself. If I keep it tensioned fairly snug it quietens down. I lowered mine though so that may help the alignment some with a smaller rear. I'm mainly on pavement and gravel; ratio works out great for what I use it for but geared way too high for single track.
