Default Re: Evo v Twin Cam Dyna

There are some clear differences between the engines. Essentially, the Evo engine has a much more efficient combustion chamber and head design, and can produce more horsepower and torque than the TC 88 for a given cylinder volume. However, the TC 88 has a better lifter design. The pushrods are straighter in relation to the valve actuators than the Evo, allowing higher revolutions. But, the chain drive that runs the twin cams is notoriously weak, and many performance builders replace it with an S&S gear drive system.



Forget about the year of the bike when you're buying a Harley. My 1977 FXS Low Rider is on the road almost every day, and I expect it to be for another 30 years. Focus on how close the bike meets your desires today in terms of accessories, colors, etc. Also consider that the aftermarket for Evos is huge! You have countless choices for upgrades both for the driveline and the chassis.



My call: Get the Evo and spend the difference on your first ride!

To me, the price sounds high on both but then I don't know what H-Ds go for over there.



The EVO is a fine motor but it's really not meant to be hopped up. If you plan on keeping it mostly stock (higher flow air filter and pipes) it should be fine. The EVO also has a more elegant old school look to it and is the last motor that can be traced back to the original Knuckle if that means anything to you.



The TC is much beefier and can accept lots of modifications. Your local dealer will probably know more about it. The young parts changers probably don't even know what an EVO is.



The chassis is the same on either bike so pick the one you really want. And grind 'em on the price a little too.

I'd get the twin cam. It's a little more modern design that addressed the problems with the Evo's like base gasket leaks, revs higher and faster, seems to breathe easier. On the down side the cam bearings could be a weak spot in earlier TC's but the '02 should be sorted. I put 8 k on an '05 Dyna last winter and had no complaints or problems with the motor, power etc.



Either one should work if that's what you're after.

And there it is. The one post to which you should pay attention.

Y'know, the price looks OK to me.. you'd do well to get any big twin for less than £5,500 then you've gotta be a bit sus about why it's so cheap. Theyre both pretty low mileage - think the Evo has about 17K on it, the twin Cam less than 5K. Probably looks worse from over there cos of the exchange rate at the moment.

That exchange rate hurts! I still have wounds from my trip to London a couple of years ago.

I vote for the twin cam. I like stock used bikes. Too many mods scare me about the bikes use by the previous owner. Mileage and condition is really the main issue to determine which price you like.
