Tokyo Biker

Hi my name is Robert, moved back to BC after 15 years living in New Zealand. Nice to be back, but the winter has been well, long ( 5 1/2 months long ) just now starting to warm up.
Friend in the UK has his son racing in the gp 125 class this year, Row is 10 years old and going very well riding a metrakit 80 and getting results. Looking at getting a new rs 125r Honda for next year, you guys have any inroads to getting either a factory Honda rs125r or a Yamaha tz 125 for the 2009 season ? They are sold in very limited numbers but we are interested at this stage ( trying to get organized for next year already ) any advice or links to a new racer with full spares kit would be a big help.
Thanks in advance Robert
I spent 15 years working in Japan so know my way around Kansai, Narita and Nagoya pretty well
