110/100-12 Front tire

[Blu]

Got my tire, date code June, 2017, excellent! got it on today. Turns out, the tire that was on there was a 110/90-12. Don't know why, there is a guy on YouTube that says that is the right size for a Helix/clone. All the documentation I can find, including the manual for my clone, says 110/100-12. That's a 10% difference in tire profile. My speedometer read 3-4 mph high, according to those speed signs on the road. With this new tire, the speedometer is dead on. I don't know why some people think the 110/90-12 is the right tire for this bike, they're wrong. Love the tire, cruises over bumps and imperfections smoother due to the wider radius, and for $40, that's basically half price for that tire.
