I'd have to agree with you on this one. I understand some folks wanting a 6 speed. I'm fine with the gearing and the 6 speed in my new Limited. Having said that my prior Harley's all had 5 speeds and I never saw the cost/benefit to ever upgrade to a 6 speed. Just my 2 cents worth.

Many thanks guys. Obviously most here like the Baker setup. My concern for the Revtec and Ultima are their ability to put up with a heck of a lot of torque (which is what I get from this bike). I'm a bit surprised no one spoke of the Screaming Eagle upgrade (about the same $$ as the Baker).

baker seems to be top O' da line when it comes to harley transmissions. i have a chopper with the ultima trans and it seems much less clunky than the harley trans in my 08 sg, but the bakers rule. if you can afford it, go with the baker.

I am running the sc eagle but for the same money, I should of went to the baker just for the superior gearing that they use. I, too have lots of torgue and it seems to be holding up so far. But like I said for the little money diff I would have rather went to Baker. In Canada, our choices are minimal, because the we still almost pay double here even if are dollars are close to yours. Stay safe and keep the rubber down. Just my.02 worth.

I have run the Screamin' Eagle 6 Speed for six years behind a real healthy 95 incher. It's been great. Same gearing as stock in the first 5 gears with an overdrive sixth for the road. It's 80 m.p.h. at 3000 r.p.m. vs. 3000 at 70 with the 5 speed. It's a great tranny and although you can get more variation in ratios from a Baker I don't think the quality is any better. Both are fine units, will last a long time, and be trouble free. Rev Tech recalled all their six speeds a few years back. Remember, if a tranny locks up at speed your rear wheel will lock up and there ain't nothing you can do. Pulling in the clutch won't help.
One thing, after going to a six speed on my hot cammed, high compression twin cam, my highway gas milage dropped. The motor isn't running at optimum r.p.m. at highway speed in sixth. It's nice to have the motor loafing at 80, but it cost gas milage, it didn't increase it.

Going against the grain here, but the S/E is your best option if you're dead-set on doing a 6-speed, which I'd advise against unless you spend 30,000 + miles a year doing highway riding. The S/E is a true overdrive, the Baker DD6 isn't. It also has less parasitic loss than the Baker, and has fewer issues. And it's almost a grand cheaper. Give Dave a call at JD's Cycleworks in PA to verify all this.
With that said, I think it's a waste of money. I've got the S/E on the 'Train, and it's a really slick-shifting transmission (like a rifle bolt). It does relax the bike a bit at highway speeds. But the $1700 I spent on it could have gotten me a 117 rather than a 103.
