Reventon R vs Reventon Pro

[brizzlemark]

Having had a look on the speed passion website the only differences I can see are the continuous current (70 vs 140A) and the programmer having a different display.

On the basis that there is £50ish difference between the two am I going to notice the difference in a SV2 when unlikely to put more than a 8.5T in it?? The difference would pay for a new motor!

Cheers.
