Does anyone have any info on this cam....seems to be a "NEW ARRIVAL"


This cam is a great match for riders of heavy Touring bikes looking for big torque at the low end. Just a quick downshift to fourth gear results in an effortless pass of that slow moving tractor-trailer ahead of you. A unique combination of lift, cam lobe duration and an enhanced cam profile ramp provides a performance boost you can feel.
This cam provides early on high torque at the low end of the RPM spectrum
The cam’s QRD (Quiet Ramp Design) delivers high torque throughout the RPM range while reducing valve train noise
Includes front and rear cams. Splined rear cam is included for exceptional load handling capability
Dealer installation is recommended and special tools are required for proper installation
All EFI-equipped models require ECM calibration (priced separately)
Recalibration is required for proper installation
See dealer for details. Labor costs not included
Gaskets and bearings sold separately

Seen these specs posted on HTT yesterday.

SE585

234/240  .585/.585   int. 18/36  ex. 47/13  99/107   103 LSA

That new 120st at 9:1 and those cams would be an excellent long term solution for the distance riders.
Looks like 234/240 duration and 31° overlap

The dyno graph would be interest to see.  I found it interesting that they mentioned valvetrain noise.  I predict that these will take the place of the 255's next year.

Perhaps if they can pass EPA with that much overlap. With a cat they can probably make it.

What  compression can this cam handle in a 103" on a 14 or 15 limited wet head.
also the VH power duels a good choice  I take it. But with what muffs to get the tq up quickly, and deliver all it can to the right

[HD Street Performance]

I cant comment on the compression until I try them and see how true they run to the calculators. Fullsac, Crusher, Rush, D&D, V&H all have decent slip-ons.

Looks like this cam will slide the torque curve out a bit. Might be a response to the 255's torque falling off so soon, and provide a better response over 3000 rpm.

Then were would the 254 fit in?

With .535 lift and intake close in the 40's, not many will care.

I have always found it very comparable to the 48.

apparently they can.  on the website, it states that they are 50 state legal.  i'd be real interested to hear how much they quiet the valvetrain down.

[Cat Eye]

The interesting thing to me is that MOCO has acknowledged that the 255 and the similar grind cam supplied in the touring bikes have valve train noise.

I am hoping that Steve at Fullsac will test them out and let us know what he thinks.

[bakon]

nice specs, but with that much lift this is not a bolt in cam. New valve springs will be needed. The Andrews 57H a nice touring cam too with similar specs and is a bolt in.

I would like to see the results of this cam AND the MR103 from S&S, would be an interresting match-up.
