Agreed with Webber - my first bike was an SV, it was restricted for just over a year, was fun and very forgiving, allowed a lot of time to get use to the power difference of the 125cc I learnt on - anything over 7 - 8K revs from what I remember tends to be a waste of petrol as you don't get much power until you shift up - derestricting is a couple of mins with an alan key - the best thing I did was derestrict my SV after 2 years of restriction
