Dealer LOCAL DEALER HAS THE 2320..

Correction:
Nuru really means "4110 and 2320 are same scenario".
According to specs though, the 2520 has slightly larger engine than 4115(81 cu. in. vs. 73 cu. in.), and the 2320 has larger engine than 4110(68 vs. 61 cu. in.).

The new machines have larger engines, but not so big boots in performance. Clean burning is not without cost. But then I have heard that the series before mine also put out more ponies per square inch than mine... Oh well that's progress!
