I have just aquired a low milage 1985/86 Yamaha XT600 Tenere with no problems to mention. However I find it wanders at speed (over 35mph) and is very easily nugged off line on the road. It has trail tyres and I have the pressures at 18psi front and back. I am missing something or is this the way Xts are?

Try increasing the tire pressures, 18psi sounds very soft for road use. I'd go somewhere between 25 -30. This should help alot!

Hi thanks for the info will try tyre pressures you suggest and report back

Changed to Mich. Serac tyres. No wandering and feels secure

18 PSI is a flat tire
