QT50 luvin!

Yellow QT50

ATTENTION: I’ve had a request to review the HPI Ignition System for qt50, and I’ve wanted to try it for quite some time now.  If you would like to see videos of the entire installation and testing process for the HPI system on a qt50, please consider making a donation below.  The information I provide can help you make an informed decision as to whether it is worth the $$$ or not.  Once I get half the purchase price raised, I will pay the rest myself.  Thank you.




A website dedicated to the Yamaha QT50 and other mopeds, mopeds and scooters. I’ve owned several Yamahoppers and also currently own a Honda Express NC50, a Honda Urban Express NU50, and a Honda Aero NB50. I created this website to share what I’ve learned about these nopeds with others and to archive photographs, videos and other information on these and other peds. I plan to document common repairs, performance upgrades, tips and tricks that I’ve come across, information on finding parts and more. I’ll learn even more from others in the moped community. Thanks for visiting and come back again often.
