No the 255 is chain driven. There are not very many late model bikes running the gear drives. I don't think you can get it in gear drive.

 

I agree completely with the above. Mine pulls ok in 6th above 2K rpm, so I just downshift until it gets above 65 and then 6th pulls fine

 

I agree completely, To me, it really doesn't matter where the tq kicks in on all these cams anyway. With these sorry *** cranks they have in the late model bikes, you have to down shift when you go below 2 grand anyway. When I'm at 2 grand in any gear but 6th, I can pull a truck. When I get between 2500 and 3 grand in 6th, I've got all kinds power.

 

Mine is an '07 with even taller gears than current models, and I can use 6th down to about 55mph, but will downshift to 5th when I need to accelerate from that speed.

It won't be cheaper if you do the job yourself. If you pay to have it done the cost of extra labor might be higher than the cost of the pushrods ($150), as it adds a couple of hours to the job.

Shouldn't be unless you have a 103 w/o ACR's. CCP for a 96" motor is 186 psi, not much higher than stock, and 203 psi for 103's w/o ACR, but all factory 103" motors have them (except the old pre-2007 CVO).

SE255 cams are chain-driven and will fit only '07 & later big twin engines--also '06 Dyna. These cams are a great upgrade for a stock (Stage 1) 96" engine, but you'll need a retune.

To all who may be considering these, you can usually find a good set of low-mileage CVO pulls on Ebay at any given time for around $150. Mine cost $110 four years ago just as they were starting to get popular, which was a great bargain. Do the job yourself, reuse the stock pushrods, and you can do the job for $200-250 if you can borrow a bearing puller/installer--or buy a Beatty tool for $100.

My results are much like most others who've reported here and elsewhere. They provide a very nice torque increase down low and in the midrange, with an effect much like taking the stock TQ curve and moving it straight up about 10 ft/lbs. Contrary to popular belief they do actually bump HP a bit at the limit, maybe 5% over stock. Statements that they "run out of breath," etc., is not something I've noticed, as mine pulls all the way to the 6200-rpm redline without peaks or valleys in the torque curve. They won't produce top-end power like most other performance cams, but most of my riding is under 4000 rpm anyway, and the way my bike runs I don't routinely need to rev it past that point.
