Talking 44t Rear Sprocket/520 XW chain

Rather than fool around with finding the 16t dampened front sprocket I installed a 44t rear sprocket. A good rule of thumb is 1 tooth in the front equals 3 teeth in the rear. A 43t rear with the 15t front is nearly the same as a 16t front with the stock 46t rear. I just wanted a little bit less RPM at freeway speed but not to loose the snap of the stock gearing. It is exactly what I was looking for.

Got the Vortex VTX-452AK-44 sprocket and the RK RK-XW-520-001 chain at www.motosport.com.

Take a look.

Question

Is this a hard swap?
I may be interested in doing this as well, as it seems a lot easier to change out the rear sprocket than the front... correct me if I am wrong though.

If you choose not to replace the chain it is fairly simple.
Remove the rear wheel, remove the sprocket nuts, remove and replace the sprocket, torque the sprocket nuts and put the wheel back on.
If you replace the chain you will need a chain breaker and a rivet type master link tool. If you lack experience with working on chains I would recommend that you have that part done at a shop.
Busted chains are a big deal on the road!

Question

will the stock chain fit fit with the new sprocket size? If so, what would be the benefit of changing the chain? I have less than 3k miles on the stock one.

At only 3k miles you would see little if any benefit. Typically you always change the sprocket and chain together, however your mileage is low enough that it is not necessary.

Nope. It's an RK XW-520 Gold. Just a good, strong, quiet chain.

I was already planning on going 15/44 with my unused original 15 CS sprocket and an upgraded chain next year... That Vortex self-cleaning rear aluminum sprocket sure does look good, but they are more expensive and wear out faster than steel one. As mentioned by Vortex:
Q: WILL AN ALUMINUM SPROCKET LAST AS LONG AS MY STOCK STEEL SPROCKET?
A: Usually not. Aluminum is for high performance and the light weight compromises longevity. The biggest factor will be the quality and care of your chain; if it is worn or poorly maintained it will wear out your aluminum sprocket."

Cool You're right.

+1 Invader.

I just happen to be one of those anal retentive clean chain freaks and am willing to compromise some longentivity for the decrease in rotating mass.

For the record though this is the perfect gearing for this bike. Just enough to take the buzz out on the dreaded freeway and not effect the snappy response out in the fun stuff.

More top end

I would like to swap out chain and sprockets. I bought my V in Dec 07 and I have put 9400 miles on it. I would like a little more top speed. I know I know if you want speed go buy a crotch rocket but its sad when a mini van passes you while you are doing a buck ten.

Sad?! Hell, what kind of mini van was it? Might have to get one of those...

Maybe it was a 700+ HP 14000+ rpm 3.5 litre V10 Renault Espace F1 minivan...
I love the way that beast sounds:


By the way, gearing change won't give you more top speed which is power limited. You just need more power, especially at higher revs to go faster.
I thought the Versys had a higher top speed after seeing some guy on YouTube top out at indicated 212 Km/hr (131 mph / ~ 120 actual) but he was going down some mountains... It does get bogged down with accessories like a larger windshield, handguards, crash guards, etc.
I'm heat insulating the airbox and swapping the inlets for larger ones, so I'll see what it'll do. I already have a Piper Cross air filter and have smooth matched TB flanges, vacuum hose mod, Muzzy header and slip-on, ignition timing advanced 5 degrees and 94 octane gas, synthetic oil... I might smooth match the exhaust port outlets as well.

Good idea on the rear sprocket. I bought a Renthal 44T sprocket but decided to return it when other forumites discovered the rubber-dampened 16T front sprocket. In retrospect, I think the rear sprocket change would have been better. I like the revised gearing, but it is just a teensy bit tall with the 16T front sprocket for some riding. Enjoy!

Invader,

Is it wrong to want a Minivan?

How about a little info on the timing advance.

The only minivan I dream of owning is Renault's F1 Espace, although it only gets 3.9 mpg (US) on race fuel...

Ok so I am limited by power. How about a turbo let me guess if you want more power buy a crotch rocket sounds like I need a Ninja ZX-10R but I dont want to spend 10,000 plus dollars on one. I love my V I just wish it had a little more top end 150 is all I am looking for so 40 more mph. I like to ride a lot. I think that 9400 miles in 8 months considering that the whole month of May I was in Cali minus one V. Well I guess the morale of the story is stop my B****ing and be happy I can only crash doing 110 rather than 150. Bear on Bicycle I was wondering how many miles you have on your V?

Bicycle Bob can you start a thread about the rear center stand. I would like a little info on the two spindles and the stand. Thank you.
