1 Down and 2 up, opinions??

[Cryoblade85]

Looking at doing a 520 conversion with a RK chain and a 14 front and 47 rear (vortex). Opinions?

Be better to stick with the 15 front and jump the rear up to 50.

[Cryoblade85]

Sorry typo. I meant 49 in the rear

Just out of curiosity because I'm not mechanically inclined. I get that if you install a bigger rear sprocket on there it gives you more "torque" but what is the stock on the rear and why jump to 50? How much top end would you actually lose on that?

Secondly, will just about any sprocket fit on the rear or is there certain specs for it to bolt up?

Just go here: http://www.gearingcommander.com/ and load your bike. You can experiment with gearing and see the affects on speed, etc.

The stock size of the rear sprocket depends on what bike you have. 15/50 is a common set of sprockets to put on these bikes.
As to how much top end you lose, it will depend on what bike you have, as the post above said use the gearcommander site to figure that out.

No, just about any sprocket wont fit on the rear. The bolt pattern has to be the same.

Stay the **** away from vortex, you will gain nothing going to an Al rear sprocket.

I went 14/50 on my 600, it increased acceleration a bit, but was a nightmare in any riding that required sustained speeds over 60mph.

How much top end would you actually lose on that?

None! It will still do the legal limit - which is the "top end" after all?? It will just scream more and drink more juice.

It would be roughly equivalent to deleting the 6th gear and starting out in about 2/3rd gear.

Makes since. So there's really no advantages? Ive been debating this for a while... I wanted something the would be put closer to the powerband becausei was told that the powerband was closer to 7000... ill just, ride in a lower gear if that's the case.

Either do that, or run a 14/50 with steel sprockets, same difference.

A mustang will never be a ferrari.

That's true. I love my kat but compared to some of the other bikes ive ridden itdefinafeky seems like I'm having to run 2nd gearing the mountain's to pull what they're pulling in 5th through there. Id like to find some way to pull some more Hp out of it though...

Sell it and buy a gsxr, it would cost less than trying to pull that amount of power out of the touring bike you ride.

Scotty has a point there.

I agree.. the smaller you get in the front makes a smaller radius for the chain to wrap around and puts more pressure on the rollers... its easier to bump up in the rear.. 15/50 is a good/popular combo..

I wouldn't bother with the 520, your not gaining anything performance wise, stick with the 530, you'll be better in the long run.

Al as in aluminum? I know the steel sprockets are stronger and last longer but I mean if they can handle the power of bigger sport bikes what wrong with it on our weaker katanas?
