You are likely talking about available SE cams. There are more cams available for Harleys than there are for small block Chevys ... LOL. There are cams available for everything in between what you describe as well as there are many interpretations of what suits perfectly, and there are cam profiles available that will show moderate gains almost entirely across the board.


This was, IMO, part of what really hurts the Japanese cruiser sales. Had Honda built their engine to be able to benefit from such improvements, likely the aftermarket would have been far more prevalent, and buyers more likely to consider a Japanese cruiser. With the VTX in particular, better head design, possibly 4 valve heads, and a better intake system could have leveraged some quick bolt-ons and easy add-ons, to show some real horsepower gains. It's unfortunate they don't like to see their engines molested like that.

Yes, factory SE cams. There are of course many aftermarket cams available from a variety of sources. But with HD's adherence to the EPA being strictly to the letter these days, it is almost impossible to get them to allow aftermarket parts that will not void the warranty. This is a very contentious issue as you know, but they void many warranties for this and essentially tell the owners to meet them in court over it.

That's smart as long as it's under warranty. And replacing cams with anything aftermarket can definitely void your warranty, no matter what the vehicle. Likely it's a good choice for you either way. Nothing wrong with the SE cams offered.

I've read posts of people that believe that the HD cams are not as good as others but personally I don't see how I could happier than I am with what I ended up with. It's an adventure each time out with it. And it lopes nicely

Ultimately it depends on what you are looking for. HD engineers aren't stupid and choose the best of all compromises, and every choice is all about compromise when it comes to can profiles. In the end they want it to be conservative enough to make a difference while still offering the best rideability, reliability and fuel mileage. They are conservative choices, as far as I know anyway, but there's more to can profiles than dyno results. Keeping the bike fun to ride is important as well. That's why the aftermarket has so many different grinds. It's all about perception and wants and needs. For the TC anyway, some aftermarket cams are very difficult to tune and be fun to ride.

I was pointing out the Todd Pierson comment because his timeslip claim of 12.02 @ 118 mph is pretty fast .

Tearing into a very expensive new motorcycle's engine that has already been well engineered. Is it worth the risk tampering into something that is reliable. Are you smarter than the engineers that built it. What if your are not happy with the results. While the Honda V-Twin line was popular no aftermarket cams or pistons parts were available, I'm not sure if anybody made them, maybe it was for the best. All I ever did to my Honda is change oil and filter. I'm still riding today trouble free , if it ain't broke don't mess with it.

The only noticeable difference is the riders, he is probably 120 LB wet, while I am a tad over 300 #, I don't know how much difference that makes. Wish there was something I could blame it on but I think my X just met it's match.
HUGE difference right there. How would he do with a 180 lb passenger to even out the weight lol

The new Rocket3 is at 169hp and 163 ft/lbs torque. An M109R could only hope. A V-Max would need to be of a more recent vintage and then it's breaking a real sweat. The new Rocket3 gives new meaning to the term "beast". Even Ducati's Diavel would have a tough time. Maybe Leroy's 1300


$10,000 isn't just for an extra 200cc, there's a lot more to the new 2020 model than that. Not for everyone though and certainly not for every budget. I'd like to own one, but I wouldn't pay the asking price for it. Way to rich for my wallet.
