ex 456 owner here
I wanted a Soul ( I had a simple at the time) but at the time they were £470 and the 456 was £125, twas a case of money talks bullshit walks £345 was a hell of a chunk of money to save.
So a 456 it was
The 456 made me ride well beyond my performance envelope and I crashed alot, it handled superbly but felt harsh and to be honest the back end hurt.
Anyway I got a deal on a CEN Soul and snapped it up sold the 456 for £95 a £30 loss in 2 years cannot be faulted
So the Soul I always ride in a higher gear than on the 456 the handleing is er not safer for me because the ride is smoother and it does not kick me off when I push too hard.
Bang for the Buck 456, but if you want a quality smooth ride with a bike that just winds up and goes everywhere The Soul wins
Go for a Soul
