Presumably this will be your first V twin? My first was also an ST2 and i have to say that it took me a few weeks to stop thinking that i had wasted £3500! I thought it was a horrid thing, lumpy, heavy noisy clutch, hard to ride slowly etc then after having a few long ish rides something kind of clicked and i would never go back to another kind of bike now.
What i am saying is that if initially you dont like it, give it time.
Yep the £40 ebay kits are a good way to chuck away £40!!!
