I bought a set of 412's from Eddie, but when bought them we ordered the shorter ones drops the bike 1". They were great when my son Brett weighed 60 lbs. but now we are scraping when he rides with me. I have the long SS cannons and now have them set to the max so Brett can ride with me.
They have 2,500 miles on them would sell them for half of what they list for and invest in another set that are 12.5.
I really like them I did the front springs at the same time and it totally chaged the way the bike rides and handles.
So if you want to drop the bike an inch and you ride solo not a bad deal.
