Nice topic

Rx3 stock front gear is 14? wouv , fit problems? 13t my stock and i fear never accept 14 very tight tolarance front place.. (13 /40 supermoto generally for road , 13 / 51 cross/enduro=first 2 gear careful

)

The RX3 motorcycles come from the factory with a 14T sprocket on the counter shaft. Since you have an identical, NC250 (ZS177MM) engine, I'm sure you can fit a 14T sprocket on your motorcycle.

Sounds like the 112 link x-ring is the one to get. Thanks

Thanx detours!

Great writeup!

I got around to installing my 13T today. Much better gearing for me on road with only a small drop in top end speed. I called CSC for the sprocket nut torque and they said 65-75 ft lbs. I torqued it to that with blue locktight (also recommended by CSC) then bent the tabs and witness marked it for easy inspection.
I'm thinking 45T rear as well for the next chain replacement.

Good for you, Lee.

I suggest you only bend one tab; it is sufficient to hold the sprocket nut. You can safely bend each tab twice, allowing you to use the same safety washer four times.

However, don't bend the tabs more than twice, or you will risk losing your sprocket nut.

Good tip Spud. I'll likely order a replacement tab for the next change as I beat this one up pretty good with the screw driver and mallot bending it flat. Mine came with both tabs very well bent over the nut and it wasn't going anywhere from the factory.

I love the screw adjusters on this bike. My last chain drive bike (Tiger 1050) was a very finicky process to get chain slack just right. And if it wasn't just right that bike shifted horribly.

Where did you order your 45T from?

I modified a sprocket carrier, and I ordered a 46T JTR811 sprocket. I can also get the 45T JT811 sprocket.

However, I just checked the CSC parts website, and I noticed the 42T, 43T, 45T and 46T rear sprockets are listed for sale.

Excellent post! I'm seriously thinking of getting one of there for Mrs 2LZ. She's a very experienced rider but since moving to Volcano, she finds her Victory Kingpin more of a handful in the tight twisties and canyons around our area and some of the "fun factor" has vanished.

So dropping to a 13T C/S sprocket doesn't effect the top speed that much? She would also use this bike for commuting on an open, 2 lane highway (65mph limit) on "casual Fridays".
What do you think going 13/45 would do to top speed?

I haven't had that experience, but I'm going to pay closer attention in the future. Thanks for that thought.

Spud,

Wouldn't it be easier to just remove some material from the sprocket to make it fit, rather than removing material from the carrier?

I really want to go to a 14/46 combo. Am not enamored by running a small 13T front. Going small up front promotes rapid chain wear. Better to go big in back.

I think you wife would like the RX3; it's a lot of fun to ride.

With the 13T C/S sprocket, you will lose a little top speed riding on level terrain. However, if you ride at higher elevations, the 13T C/S sprocket actually allows you to maintain a higher average speed. The better torque allows you to maintain speed without down shifting.

The stock rear sprocket is 44T. If you get an RX3, I suggest your try a 13T/44T sprocket combination first. The 45T and 46T sprockets help a lot if you are doing more technical riding at higher elevations.

If you are a machinist, and you have tooling to cut hardened steel, it might be easier. However, it was far easier for me to trim a little aluminum from the hub once, rather than to cut hardened steel every time.

CSC is now stocking the 42T, 43T, 44T (stock), 45T, and 46T rear sprockets. Therefore, you don't need to modify either the sprocket carrier, or the sprockets, if you buy your sprockets from CSC.

i have found that 3rd gear works well on the dirt roads around here, but it seems that it is geared a little high have to down shift on the hills we have lots of them 2nd seems to low. should i change to 13t on front and leave back alone bike will never see the freeway would like to keep stock chain bear in mind i am new to all this a 3 day safety course and 400 miles is what i have for riding time but i bet i have biggest grin you all are very helpful
