Throttle response

I was a bit disappointed with my 04 955 speed triple when I first got it, I thought it was a bit flat, I know it has less power than my Aprilia Tuono but I expected a bit more go. I eventually realised that you have to give the throttle a really big twist to make it go and was a lot happier with the performance, but you only have to touch the throttle on the Aprilia and it's off. Is there a quick action throttle available for the Triumph or a throttle from another bike that will fit to give better response without so much input.

 

Thanks for the replies, I'll probably leave it for now and see if I can get used to giving the throttle a bigger twist, if not I'll look into your suggestions.
