What do you mean by "upgrading to a full sus"? personally I'd call it a downgrade.Until I'm aged about 80 I'll continue with better handling and greater climbing ability. Downhill speed doesn't bother me.
[Rob Edit] - cleaned another thread and created this one.
Great to see this Forum up and running.
I have a 2 year old Haibike Sduro Done approx 4000kMs. Just fitted new Manitou Mattoc forks and this has made a huge difference.
Love the Yamaha motor.
