Six speed transmission for sporster
HI:
Although I have been riding a sporster for a while, I just realise that my 2004 XL1200 kind of needs a 6th gear for long trips.... Does any one know if there is a 6 speed transmission maker? anyone feels the same?

The stock 2004 US model came with a 29T counter and while running down the road at 70mph my tach would read roughly 2,900rpm. The International model came with a 30T counter, which on my 2004 R model dropped that 70mph RPM down to just over 2,600. The counter pulley runs roughly $65 at the dealer. I currently run the 28T pulley from the 883 and at a heads up 60mph I'm running right at 3,000rpm.

Stock US 1200's, 2004 up standard gearing, at 70mph turn ~3400 rpm.

+1 - and changing from a 29T to a 30T would give you about 72.4 mph @ 3400 rpm.

"Driven" divided by "drive" gear for the ratio; after that I'll leave the math to youse guys! LOL Ditto on the price; cheaper to go with a primary or drive gear pulley ratio change since changing the gears requires splitting the cases since trans "door" was phased out. Problem is you sacrifice low end for high end, etc. so it's a give or take.

Tell ya what, why don't you come over this way and you can tell my bike and its factory tach about the new math because it isn't buying it at all. The change from the standard 29T to the 28T drove the tach up roughly 400 rpm. The change from the 29T to the 30T drove it down in the same manner. At present, 60mph will give me just under 3,000rpm with the 28T. At 70mph with that same 28T counter I am running pretty close to that 3,400rpm mark at 70mph. With the stock 29T pulley I would be closer 75-78mph at 3,400rpm and this isn't using one of these off the wall gearing calculators. It's what the tach is registering on the bike. I would rather believe the tach..

There is a company (of course I can't find the name offhand) that makes custom rear sprockets for Harley's, in either chain or belt versions.
Allows you to go with more or less 'teeth' and gear more towards low end grunt or lower RPM top end cruising.
EDIT.....
I did find the company, which is Supermax Products (link below);
