2017 EC 300 vs 2008

[5valve]

Was offered good price on the new model, don't yet even know if it's E or what type suspension is it equipped with; reiger/marzz , sachs/sachs etc.
street homologated version.

Interested in comparing:
- Weight, reports say 2012on models are heavy feel
- maneuverability in slow trecherous offroad, mid steep hill starting & mx track experienced amateur usage
- ease of engine setup is prefferably the same as previous models, squish, compression, jetting
-AS2 without TPS i hope
- plastic subframe prone to breaking? alu is easy to weld.

any other live usage data valuable info.

I know powervalve is adjustable since '15.
