I was given the Lego Technic Motorbike set as a Christmas present, and not having built anything with Lego Technic for many years was looking forward to seeing what, if anything, had changed since I were a lad.
The set comes with two seperate sets of very detailed instructions - one for the motorbike model on the front of the box and also a second, slightly different, motorbike. I found the time to make the main model and was impressed at the increased number of different bricks and other bits that now make up the Technic range. Sure, some of the bits (such as the cowlings) are there to make the model look good, but there is nothing but your imagination (and lack of time!) stopping you from making your own models with the pieces in this excellent kit.
It's not cheap, but you get a lot of bits of Lego for your money. My only real negatives were firstly that the model doesn't really stand up nicely on it's kick-stand so can't be used as an ornament should you wish. Secondly, Lego boxes don't seem as substantial as they were when I was younger, so it's not really the best place to store the bits in again once you've taken the model apart. I've noticed the same thing with the Duplo sets we've brought for our son.
These are only very minor negatives, and overall I would highly recommend this Lego set.
