When we test road the Freewheeler trike last month before buying I noticed a few things.
1. It had plenty of power smooth throttle response no hick ups and tons of torque.
2. The stock muffler tone was pretty darn good nice and throaty considering there maintaining a legal tone. To me the Freewheelers mufflers are some of the better sounding stock mufflers I have heard on a Harley
3. The new air intake produces 15% more air according to Harley. If you look at it closely you will see a big screened opening with a snorkel design (pretty much a cold air intake).
With all this said I was pretty happy with the trikes factory performance. So I think I will leave it stock for a while and just put in a factory replacement K&N filter and ride.
Harley did a pretty darn good job with the Freewheeler in my opinion. Considering all the EPA rules while still being able to make the trike perform well in the stock configuration. Again
Just My Thoughts...
Ride Safe All,
