Sprockets

[AK Tiger]

I have an '05 Tiger.  It's time to change the chain and sprockets.  Where's a good place to buy them?   I'm looking for a 19 front and a 43 rear.  I'm getting ready to do a cross country ride this summer (California to Prudhoe Bay, Alaska to Key West, Florida and back to CA.) and would like a higher, lower numerically, final drive ratio.

sprocket specialists

they are in California too .

the front for up to an 06 tiger is #598-18 but yo can get 16-20 tooth
the rears can be ordered in any size you want 2693-xx, although I believe they are aluminum alloy . they are tough as steel though . you can get the steel ones in 43 and 44 tooth  2693s -xx , the steel ones are only $34

you will have to adjust the # of links in the chain to match whatever you use for sprockets
the stock chain length is 114 link
for what you want to do I would go with a 18t front with a steel 43t rear
a 19 front is gonna make for an awfully tall 1st gear

Thanks for the quick reply Mustang.  I'll give these boys a call.  

I had an '02 Tiger that I ran with for about 28K miles with a 18 tooth front and a 41 rear.  That was a 10.86% change from stock.  My thought was that the 19/43 combination would be an 11.44% change and that a larger front sprocket (19t) might improve chain life.  Of course chain life reallly isn't as much of an issue with the new chains as compared to the old stuff.  

I'll carefully consider your gearing suggestion as 1st  gear did require a bit of clutch slippage to get going.

Thanks again

Hijack...sorry.

I'm going to change out my sprockets before my trip to Banff this summer.  I'm happy with the stock ratio.  Any recommendations on a brand of sprocket and chain I should replace them with?  I'd like to change them out this winter while I have less riding time or more sitting time.

sproket specialists make good stuff
JT has the steel ones for tigers I usually get JT sprokets for the rear of my tiggers from Dennis Kirk
EK makes good chains that won't break the bank
DID is a real good chain but are usually considerably more money than an EK of comparable strength

Thanks again, Mustang!

Thanks a bunch Mustang!  Have a great 2010!

Didn't Stretch run a 19/43 combo? I was worried about having too tall a first gear, especially on the gravel, but have to admit I'm always looking for 7th on the highway

I run an 42 tooth rear, haven't looked at the front as I got the new sprocket cheap and just replaced that. mine's an '06, and other than a trifling little bit more clutch slip, it's works very well for reducing rpms and vibes.

FWIW, I ran a '96 Trophy with an 18-38 combo, had noticeable slip on the off, but the bike was smooth as silk from then on. Seems it moved the vibration period to Mars, and the mileage went from 38 to 44mpUSg.

Im running the 19/43.  Have been for 10,000+ miles.  Honestly I wouldn't have it any other way.  Dont know how you guys do it with stock ratio, which lasted only weeks till I went with the 19, its the first mod I did on my bike.

Still plenty of off road worthy.  Definitely more than the Tourances can handle and up to the limits of the Tiger, It's not a Husky 610 and will never be.  I go through fields, fire roads, rock levees, through the unmowed grass to the pond, woods, etc.  No slippage required to start off from stop signs or driveway.  Minor feathering only when going to the pond.  

This is the first I have heard of a 20 being availiable.  I thought 19 was the biggest.  I dont know the rev's exactly offhand for the 19/43.  I think 5,000 is 82mph, pretty sure I posted the revs awhile back.  It's right where it should be, very managable in parking lots and on the freeway.

I did not have to modify stock chain to go to the 19/43.  Infact I haven't ever had the chain off my bike  :?

to clear up a little confusion in this thread .............

here's the numbers

stock steamer final drive is 18/48 or 2.67to 1 ratio
           steamer with ........  19/43 or 2.26 to 1
a steamer with this final drive needs clutch slippage especially loaded or starting on a uphill incline

stock Girly tigers are 18/46 or 2.56 to 1 ratio
         Girly tiger with  19/43 is 2.26 to 1

the 955 can withstand the lower gear ratio better because it does have more torque output from the engine .

I don't know what the 1st gear ratios are in the transmissions between these two bikes are but I would assume they are different . just as the 1st gear ratios in a 1996 trophy are different then the 1st gear ratio of a 1996 Tiger , which will have an effect on the bikes ability to pull the lower gearing of the final drive

two up with loaded saddlebags ........YMMV

Thanks for clearing it up Mustang.  Hope you're out riding today....it was -23F at my house this morning when I left.....I took the VW! :shock:

FWIW:  The gearbox ratios for a 955i Tiger.

1st   2.733
2nd   1.947
3rd   1.545
4th   1.291
5th   1.154
6th   1.074

went and looked it up
the steamers are the exact same gear ratios
and my statement about the trophys was incorrect they are the same ratios also
even the lowly 5 speed thunderbird boxes were the same gear ratios just missing the 1.074 sixth .
hell even the big dog 1200's were the same ratios ,daytonas and sprints too !
even the 750 trident had the same gear ratios

I think the stock size for the 1999-2000 Girly was the same as the steamer.... 17 / 48... I suppose you could go by displacement? 885s would be 17/48 and 955s would be 18/46.
