Two weeks ago I bought this 2003 Motor Trike Solid Axle with 21,000 miles on it. I've put about 600 miles on it so far. My butt started hurting quite a lot, so I got an Airhawk R and that helped a good bit, but riding my bike to work this morning (85 miles) my butt still kinda hurts.I changed out the oem air shocks with ones from Airbagit and that improved the ride somewhat - especially handling. however, I might have a small leak somewhere, so I gotta spray them with some soapy water and check for leaks. I'm guessing it's in the oem fittings, so I'll change those out.I really wanted an IRS trike, but this one was in my price range, and I do like the simplicity, reliability, and handling of the Solid Axle.I paid $14,000 for it. Did I get a good deal ? It sure is pretty. I have NOT ridden an IRS trike, so I dont really know how much better the ride would be, but is it $11,000 better than a solid axle ??? i'm guessing it would cost me that to convert it to IRSAnyway - all comments are very welcome !!! Cheers
