I upgraded to RR level 1. The biggest difference I noticed at first was the front didn't dive as much and didn't bottom anymore. After a year I took the rear absorber to a work shop for service. As I waited to get the absorber back from service, I installed the original absorber. O'Boy! What a difference. It was a real downgrade. Bike was almost undrivable. It was a relief to get back the Tractive absorber. That's when I realized where I put my money. It's really worth doing the upgrade. The best thing with the cheap suspension components on the G310GS is that it doesn't feel so bad to change to after market parts. On my old R1200GS one of the OE ESA shocks cost half the purchase price of a G310GS. It sucks to have to buy a new because the absorber can't be serviced or repaired.
