Cheers both, gave Bike Sport a call and they confirmed that they're not compatible, 'very differently wired' was the reply
Oh right. If you want to buy switches for our bikes. Give Tom a shout https://www.motorcycleraceparts.co.uk/ Say I sent you. He will do some good deals for Trioptions riders
I had a big box arrive from Tom last week. I'm not that bothered by using the standard switchgear to spend 'new' money, this was just a potential eBay bargain that popped up but alas its not be.
