Joe, seems like you are the fastes replyier of the group.
you beat me by two seconds...hehehe
Kevan, I will totally agree with Joe. The 1/12 scale is much more satisfying and could be easier than those 1/24. Just try to buy an older model for start,from Tamiya line. I would recommend a Honda 750 or a katana. they look nice when finished and do not have any complicated process to build, very straigh forward.
I have build only one old GP bike so I can not tell you if the more modern ones are easy to build.
Any how, if you have any question/doubt/problem during the build process, do not hesitate to ask here .
Good Luck
Edgardo
