Believe me Robert, you're not getting old. I'm 62 and been riding since I was 14. I've lifted the front wheel of all manner of bikes, but with the R3T all I seem to do is break the rear tire loose. Probably has something to do with that 180 rear tire.
Of course I haven't tried yanking the throttle wide open at 10-15 mph though. On most bikes I've had in recent years that would certainly bring the front wheel skyward. I wouldn't be too concerned about the 750 lb beast coming up, but coming down is another story....
