Decoding a 2005 Honda

[slow_bloke]

NADA says that for 2005 Honda 50 there's these models:

1. 205 lbs = BF50A5LHTA = LH Counter-rotation ?
2. 213 lbs = BF50A5LRTA = RH Standard - rotation ?
3. 205 lbs = BF50A5XRTA = ?
4. 205 lbs = BF50A5SRJA = Jet

Are my assumption correct for the first two in the list?

Anyone know what differentiates the BF50A5XRTA model?

Thanks in advance.
