14t Sprocket

[flanman]

Just wondering the benefits/drawbacks of the 14 tooth sprocket. I imagine lowend is better but how about topend? Any real noticable differences? Thanks for any insight!

You lose a couple MPH off the top of each gear, collected it probably makes a loss of 5-10 off the tippy top.  But even on a 620 it's still quite capable of breaking an US speed limits

Low end will be improved noticably.
 I went up 3 in the rear and down 1 in front, now she comes off the line like a rocket.
Top end is still over 105mph. Plenty fast enough for me.

It's a really cheap mod every Monster should have. 

Wouldn't they come this way from factory if it wasn't for some European noise rating?

This s a cool site that pretty much has all the gearing info you'd want.

yep, did it on my S2R 800, huge improvement off the line, specially with 2 up

I just added the 14t sprocket this past weekend.  I had about 13k miles before that without.  The 14t sprocket makes my bike run in higher rpms in general, it seems -- which makes the lower gears like 1st and 2nd run much smoother.  I noticed less chugging.  My top end was taken away slightly but I spend most of my time between 0-65mph rather than 90-120mph.  That's why the 14t sprocket was a good mod for me.  I haven't noticed much difference in gas mileage yet.

Just installed mine last weekend.  I noticed that pretty much all of the lugging is gone and everything feels much more smooth.  Really makes the thing a lot more fun.

I do notice shifting a bit more, but the shift points seem more natural. 

A whole new bike really.

+1 to what everyone said.

The 14t all but eliminates the lugging at low speed. When I did mine, I went up 2 in the back too. But the 900's were geared pretty tall to begin with.
I used the opportunity for a new chain as well. It makes 6th gear a lot more useable, and I didn't notice any significant top speed loss, but then again I'm not looking for my top speed anyway.

I'll take torque over top-speed any day...The 14T was a no-brainer for me in that regard.....I almost feel like I could go up one in the back but I'm happy for now...

That site is cool - and the best part is I had no idea my 620 would do 205 mph!
140 be damned!  ;:|

On most of my bikes, it does not feel like I lost any top speed at all--I just get up to top speed a lot faster...: )
With a taller geared bike, it takes so long to get up there you run out of safe space to do it in most cases...

I think aerodynamic drag is such a bigger factor in top speed any way.

Jim (the Gearing Guru) used to say that in some situations shorter gearing could slightly increase top speed.  If, for example, a bike couldn't max out in top gear because of wind resistance.  Shorter gearing might help that bike get on top of the power curve in order to eke out a couple more miles-per.

This is not a problem with the 620, as it is proven to top 140mph bone stock.

I'm thinking about doing this mod, but how hard will it be to install with my limited wrenching experience?
Is there a guide anywhere?  I don't mind experimenting, but don't want to screw anything up.

[Jnaids07]

Hardest part is getting the chain tension right after.  Thats it.
