RE: 06 vs 07 durability
It must be nice to have the greenbacks to trade an 500 mile '06 for an '07! You go, brotha.
As to longevity, I don't think I'd worry about either the stock '06 or the SE '07. A major design requirement for the Twin Cam was that it be built strong enough to allow customers to "hotrod" it, worry free. That makes for more SE parts sales!

The longer stroke decreases the piston speed, durability ensues by principle of mechanics.

But on the whole topic of durability, as stated earlier, these motors should both be plenty durable. I've got a TC88 and I'm happy. I plan to do some performance work to it in a few months and I will want the better revving motor so the TC88 is probably a better fit for what I would like to do. If I was going to keep the engine mostly stock, I'd certainly prefer the TC96 and I wouldn't worry for a second about its durability.

Longer stroke does INCREASE piston speed. More area to cover, 3/8 of an inch more to be exact. This builds more heat. Personally, I don't think the marginal difference in power is enough to notice and I don't think it's enough to where the bike is going to run easier on itself, the piston will have more distance to cover up and down to run at same rpm. More heat and more wear. On a lot of stroker kits for the TC88 the increase is only 1/8 or a 1/4 inch more than 4 inches. I was surprised to see HD went up to 3/8, I figured that was the limit in reasonable stroke increase.

The increase in inertia from the longer stroke is well balanced by the lighter pistons and con rods. The bore to stroke ratio is more in line with the pre TC88 engines. But let's face it, HD was very smart in increasing ther stroke because they have a clear shot to 103 inches with off the shelf parts.

My dealer told me that the new engines are a bit louder in the valve train area, straight cut gears, so alot of people may notice it. Also they said H-D made the exhaust a little louder to over come this. Any thoughts to this...

RE: 06 vs 07 durability
Before you rack your brain thinking of benefits and drawbacks for why HD would add this last year or take away that for this year, remember that a lot of their motivation is money and the bottom line for shareholders. Many of which ain't into riding I'm sure. Instead of asking the engineers if this part or system is a good one to improve on, add, or drop, they probably ask accounting.
I know it's not much, but the prices for 07 did go up by $500 on most models, Bobs included. I'm happy with my 06 and I bet down the line that motor, if left stock, will prove longer lasting than an 07.

RE: 06 vs 07 durability
for 8ci more it would be a da.. pricey move to even think bout trading a 06 model in on same 07 model.My guess would be a dealer couldnt or give more then 9500 for a 06 fxdi then you eat2700 there plus freight setup also plus tax tile licence fees.think id rather take 2 or 3500 and have a real puller out of the 88ci.
