Amazing, thanks Rob!you can by pass the rear brake part on the pump so you have a good rear brake without abs, here you are page 2.
Yamaha North America gave me some really good info...... They wanted to have one of their guys check it out, but they did not have anyone (or money) to have it checked out. So the dealer becomes their eyes.....then they told me to work with the dealer. So they never looked at it after saying...yamahasupertenere.com
On my to pick up some copper brake hose now and get the rear bypassed. Will go easy for the first few miles to get used to it but that sounds like it's the perfect solution for me. Bought the bike for £5k with 18,000 miles on it so was expecting to find a few issues along the way but not one that would cost me a few thousand.
Amazing how quick everyone is on this forum with fixes, it's invaluable! Makes me not want to ever sell the bike as there's surely going to be someone who has experience with every issue possible!
Now to find that pesky 10mm ring spanner I put down nearby just a moment ago...
