I had the same problem. At speeds above 95 MPH (150 KPH) the front would start to weave and this sensation increased with more speed to the point where I would have to roll off. Anything above 110 MPH (175 KMH) and the weaving seriously caught my attention! Taking one hand off the bars helped calm things down although this is a little counter intuitive! My bike was on stock settings. It was not tyre related as I've swapped the OE Dunlops for Michelin Pilot Road 3s but had the same experience on both sets of tyres. I wondered if it was aero related as it seemed worse wearing loose clothing / bulky jacket compared to riding in leathers. Whilst I think there is an aero element (as you would expect with a tall, flat bar bike with a crap screen!) I wasn't convinced this was the real issue so I had a look at the suspension. My bike came from the dealer on stock settings but I am over 100 kg in weight and quite tall at 6" 3' (1.91 M). The suspension is very soft on stock settings. I increased the rear pre-load from 4 to 6 notches from soft (1 off max) and increased the damping from 1.5 turns from fully in to 1 turn from fully in. At the front I increased the pre-load from 16mm of adjuster showing to 12mm. I left the damping on 7 clicks from fully in. This transformed the bike. Steers better, holds a line and more importantly the weave is pretty much gone. It still weaves a little bit at speeds in excess of 120 MPH (190 KMH) but I'm pretty sure this is aero related as the wind catches my shoulders and wags my arms creating un-wanted steering inputs - that screen really is rubbish! So basically the Tracer needs setting up for each individual rider especially if they are big / heavy. I have never had a road bike that is so sensitive to suspension settings and I think Yamaha dealers need to get hold of this issue because I'm sure some folk will really be frightened by this bike on stock settings. Once sorted I can honestly say this is one of the best bikes I've ever owned. Hope this helps.
