The tomberlin version were originally imported by Moto scoot in Milwaukee, they were 49cc from the factory but a lot of them got 70 kits installed by the dealer. From like 06 to maybe 13? Moto scoot imported them, at some point the 125 came out, maybe like 10?
They have some decent components on them, but they are so heavy, like 200+ lbs. They are also geared painfully short from the factory.
