Tom, hello and welcome to TBN. I do not think at all it is verbotten to diss the BX, in fact several have taken it to quite a high level of refinement. Nonetheless I am sure you will enjoy your new BX with or without a cheesy steering wheel. I imagine that the wheel from your TR250 might work--huh? Seriously you might also look at the wheel from the 2410, it looks like it should fit my BX (I got a 2410 also) Actually, the steering wheel works fine but I do know what you mean about the center cover, nothing is perfect. Have fun.
