Re: st-digest V2000 #354



Jim,

Thanks for the reply.  My wife Jan and I (Don) share a mail account
for the time being.  I've updated the name to be less confusing.

These tires are for the street mostly.  I have an RS, not an ST.
I think, from the test rides I took, that the stock RS suspension is
quite a bit stiffer.

I'm thinking of running back-to-back test loops with 32 front/36 rear
and then 36 front/42 rear and reporting back to the list on my impressions.

|     Is that for track or street?  All the tyres for my T3 Daytona and

|     With standard ST suspension I think you could ride with solid wooden

|     I wouldn't have thought so.
