15 minute job - watch the videos! - just needs a 10mm spanner and socket.
New levers look really good; shortoies are about an inch / 3cm shorter but feel very comfortable and controlled using two fingers.
I bought a new 24 Tiger 900 RP Range and the Evotech solution is excellent. The alignment and replacement bar is clever and my Garmin Nav is sitting perfectly above my TFT. I have not lost the ability to raise and lower my shield. Excellent video instructions.
