Modern Buddy

Anybody know of other upgrades to the 170i, other than the engine/FI?

I bought my wife a leftover 09 150 for Christmas. I'm looking at a new 170i and it appears that the rear shock may be longer and most certainly has more rings of springs around the shock.

Just to help people who click on this thread, what types of upgrades are you looking for?

Hey Rusty, Stock improvements over the 150 carb model. Obviously 20ccs and FI...anything else?

My wife has an 09 150, I'm thinking about the 170i. Looks to me that the shock is slightly different. Looks either longer or the spring is wound differently or uses thicker steel. Can't figure it out but thought others with more Buddy knowledge might be able to provide insight.
