I fitted MT21s recently mainly because they are reasonably priced and I've covered many miles with them on other bikes.At first I was rather dissapointed in how they feel on tarmac, certainly nowhere near as good as when I had them on a DRZ.
After playing around with the pressures and dropping from 30psi to 25 they felt better.

Whatever, much better than the motorcross front I had fitted previously where the phrase ' handles like a pig on stilts' comes to mind.

Offroad I can't fault the Pirellis and conversely they suit the Tenere better than the DRZ. Possibly down to the extra weight and smoother power delivery, getting very little wheelspin and less front end slithering at low speed in really sticky mud despite running higher pressures than I would normally.

But given that I'm doing a fair bit of road riding also, sometimes with a pillion, they are too 'offroad' and spoil the Tenere's handling on tarmac.

Good job I have a very large tub of tyre soap.

Here's a pic below for anyone who hasn't seen the Pirelli for comparison with the TKC posted in the other thread.

Now after a few hundred miles they have improved vastly on tarmac.They still spin up easily in the wet and the front starts to 'wobble' above 80mph but both can be avoided with a gentler throttle hand.The wobble may be because I still have the old balance weights fitted.................. must remember to prise them off.

I'll report on wear at a later date overall I'd say they do the job well.
