Hey everyone. First timer to this forum stuff so if I'm posting in the wrong place don't be scared to steer me in the right direction. I'm putting a deposit down on an mt07 next week and am pretty excited about it too. I've only ever ridden dirt so I'm excited about doing some street riding on this animal. The question I have is, about the power to weight. I know it's very close to the lams limit and was wondering if an akrapovic pipe would make the bike technically illegal for a learner because of being 3-4kg lighter and I believe it gives e's a small power increase. Thanks for any replies in advance!
