Here in Oz (and I'm assuming the UK) the Sportline comes with a re-flash of the ECU, displaying 'RACE' on the ODO when you switch on. The exhaust is also stamped with 'Race Only' (or similar). This is no doubt due to the lack of CAT(?) Obviously this makes it technically illegal for road use. I do however run mine with a Sportline and I keep the baffles in, I wouldn't say it's too loud, a lower grumble than the standard pipes and a few more pos and whistles on decell – I rode it back from the dealers with the baffles out and to be honest it wasn't that bad but I'm all for a peaceful neighbourhood 🙂.
