I was at the dealers on Friday and got into a conversation about the Arrow Low Boy for my '05 1050 but at £842 plus labour it's a serious investment. I've been looking around and the MIVV looks interesting and apparently runs on the standard map and is I assume a slip on low can - at about £300! I have seen some reports on here of torque loss which is a turn off, but would welcome comments. The stainless X-Cone is even cheaper!
