Experienced that before and a new tyre cured it. Just recently was experiencing it again. The tyre was worn again and I assumed that was the cause. I suppose it is the cause, but after replacement, I still have a very slight oscillation. Here's my theory - The original Metz was a 'LAZAR' the last two where the upgraded version - 'LAZAR TECH'. The tyre is much the same with upgraded compounds I believe. The original suggested PSI was 36 which I maintained. The Metz site fitment chart indicates 40psi. I am going to up the pressure before I get permanent cupping and see if the vibes subside. If there's any marked change I'll post. May not occur till the week end.

I finally got to play with the pressure and take a good ride. I raised the pressure from the 36PSI Triumph recommendation on the neck and manual to the Metzler recommended 40 PSI from the Fitment Chart on their web site. The wobble ia ALL BUT gone. There is the most slight wobble at about 43 - 45 mph. So, it seems two factors are at play - Tyre wear (i.e., cupping - Mostly due to low pressure flex and wear), and inflation (which seems to have from the 36 PSI of the original ME-33 Lazer to the Lazertech replacement. Anyway, thats my story - and I'm stickin' to it.
