Sprocket Ratio info

[Suzukidave]

Front sprocket as follows:
J,K,L models 15 tooth standard (16 optional).
M,A models 16 standard (15 optional).
B model 14 standard (Suzuki gave no options).

Rear sprocket as follows:
J,K,L models 47 standard (43,45,49,51 optional)
M,A models 43 standard (45,47,49,51 optional)
B model 40 standard (Suzuki gave no options)

J,K,L gearing was all the same, ratio`s not changed until the M model then again on the B model. Anymore or less than 3 teeth will change the gearing noticably. In Germany B had a 15 teeth front sprocket!

The best overall gear ratios for most purposes on all series are 15-43, 16-45 or 14-40.

These ratios will give you a top speed of app. 115 mph and good acceleration.

Tim on the UK board also put together a good chart which he graciously allowed me to repost at this link - check the link for the gear ratios and MPH.

Oh yes mo better

That is too funny. That is my chart that was posted http://pinkpossum.com/GT750/GT750%20gearing.pdf" onclick="window.open(this.href);return false;

That was generous of Tim to allow you to link to my chart on his website. Cheeky beggar.

This is pretty cool and invaluable with my Kawi race bike. It actually already has a lot of the sukis including the 750. Compare gearing, speed in gears, super easy to change gearing spec and max rpm.

Oooops I'll update the credit Richard

Done

Thanks Ian. I was just amused or should that be bemused. It's quite a common occurrence now to see articles and particularly pictures re-posted in different places on the web. Glad to see that it's useful to someone.

I think I'm currently running 15-43 on my L and it's pretty much perfect for acceleration and mileage.


Chain/sprocket wear seems good too.

BTW, the larger the front sprocket, the better.
Even though a 530 chain is not that large, you'll end up with appreciably more heat and wear if you make it turn tightly over a 14-toother compared to a 15 or 16.

And, it's not a bad idea to have an odd-numbered sprocket in the mix as wear between the chain and sprockets will be more even.
The same rollers will NOT be hitting the same teeth all the time.

The gearingcommander site can calculate this all out for you - highly recommended.

It was me that provided the site owner the specs for GT750's, BTW...

It gets curiouser and curiouser.

I thought I got info from several people, checked those answers against a whole slew of magazine articles from back in the day, and then created a simple spreadsheet, which by some strange coincidence is still on my PC in its original form.

I'm sure that many people have constructed the same or similar data from input from many individuals over the years. There's not much that's proprietary about the data, and it's all about sharing and spreading the knowledge around and passing it on to others.
