Default 5 speed final ratio chain conversion

For anyone who's converted over to chain, I'm interested in hearing what combination teeth sprockets you used for transmission and wheel sprokets, and how you found it to ride around town or on the highway etc. cheers

Ps i rarely get much response in the workshop threads on here so that's why im posting it here

Not a belt to chain experience that you are looking for but falls under different gearing than stock.

I went from the stock 5 speed (2005) to a Baker DD6 (3.24 first gear) with a 30t transmission pulley. 1st gear is useless (need to shift mid-corner from a dead stop) and 6th gear feels like 5th gear from a stock transmission.

Unless you just want to bar hop around town, stick to 32t transmission sprocket.

I don't think 32t in a sprocket setup would be a lot of fun. I think you are meaning pulleys to run a belt.

Sprockets on a 5 speed from what I've read are good between 19-24t. I'm wondering what a good happy medium would be so I'm after anyone with setups they've had experience with. Belt tooths are hard to compare speaking in teeth terms

Did Baker advise you on the internal DD6 gear ratios along with your planned secondary ratio changes? Gearing is all math based, there is no reason to guess or end up with a less than optimal result. I'm sure your too short gearing can be fixed with a smaller rear pulley. if you want some help post up the 1st-6th gears in the baker, your primary gear ratio and the secondary pulleys (we know you have a 30t front but what's on the rear).

2005 bikes already came geared very well with a 32/70 secondary drive ratio. Baker tends to run their gearing a bit shorter in their transmissions,typically already optimized for a 32/70 stock setup. so without guidance from Baker at time of ordering the DD6 it very well can end up feeling too short overall with a 30t front. this could be as easy as dropping your rear pulley to a 66t, if you have about 3/4" of rearward belt adjustment in your slot. going to a 66t rear pulley will give you 6% taller overall ratio gearing and you'd effectively "un-do" the 30t front pulley change in ratio.

for chain drive swaps, use the online calculators to figure your gearing before you buy parts. you can input your own specs, load similar bikes, etc. you will know your exact ratios, rpm at mph, shift points, etc. - With a chain swap I would select front / rear sprockets that provide the same secondary ratio, or maybe 3% shorter ratio, than the stock belt pulleys.

{EDIT} - to the OP, if your bike is 2007 or newer, get a chain sprocket combo that is 9% to 12% shorter ratio than the stock 32/66 pulleys. If your bike is 2006 or earlier, get chain sprockets that are the same ratio or 3% shorter ratio than the stock 32/70 belt pulleys.

It's a '96 5 speed. I'm not I'm to speed with the ratios for every model some I'm not sure what Im working with. It's a new build I'll be starting on soon, just collecting parts now. It's not a stock tranny eithe by the looks it my be an Ultima or revtech 5 speed. It does feel much shorter then my 07 6 speed, so I don't want to get crazy with shortening it too much. The bike will be much lighter, and it's a 110 cube, so Im crossed up on wether to go for a stock like ratio or a fraction shorter. Thought I could go a smaller sproket on the tranny and if it's too short then thro a larger sproket on the rear to save the effort of pulling the primary again

I was hoping some ones already toyed with these ratios already on the earlier5 speeds and could just tell me straight. I looked into those calculators and there's a lot of info I can't find to fill it in properly so I'm here hoping for a quick answer

Ink83 - still running a belt. Just giving you a real life example of what happened when I dropped the front pulley down 2t from stock.

LA_Dog - rear pulley is a 70t. I spent a lot of time working the numbers on Baker's RPM Calculator but that only focuses on the last gear (5th for stock, 6 for OD/DD6). Next time I the inner primary is off, I plan on changing the front pulley out.

I do appreciate your input thanks mate. I think you've comfurmed the suspicion I had, I should run a close to stock ratio. Adding to it the larger displacement and the extra weight removed, the stock ratio of the old 5 speed should really come to life with out sacrificing highway cruising

32/70 belt is a 2.18 ratio

The most common trans pulley for a chain is 23...the most common rear pulleys are 46 48 51

23/46 is 2.0 ratio

23/48 is 2.08 ratio

23/51 is 2.21 ratio

I would go with the 23/48... you will have no problem pulling that with a 110 CID...you will really like it on the highway...if you decide you want shorter...simple to throw a 51 on the rear.

I could be wrong but I think the earlier 5 speeds like in my 96 heritage are geared taller? I spoke to a sprocket company that have said a 24/51 would gear me as close to stock (2.11) as I'm going to get with my year 5 speed. The 24/51 is meant to be a fraction shorter then stock at 2.12. I'm only going by what I was told, I could of heard wrong or been told bullshit.

Right now stock it feels th me like not enough low end and revs to much on the highway, but I'm use to 6 speeds.
The bike will be at the very least 50lbs or more lighter as well, so maybe the 2.08 as you suggested will be a better number

You will not solve that with a gear change...anything you gain on one end, you will lose on the other. If you don't have enough low end with a 110...you have a tuning problem...or too much cam for the set-up.
