Popular knowledge, or opinion, on this site is that the bias ply Shinko 705 are likely to have problems such as block separation, whereas the radial version are less likely to have them. (as mentioned by Oldschooler).I haven't been an advocate for off brand tires in the past but at this price I could be easily convinced.
Shinko-705 110/80-19 (Front) & 150/70-17 (Rear), October Sale - Aviciouscycle.ca
Take note this thread is posted in tha Canadian area, eh.the price is great, until you factor in the shipping
motorcycle-superstore ships free & my new rear was just 89, from them
as for the quality of the 705's, my experience w/ my 1st set convinced me to buy a 2nd rear after 6500+ hard(not into the wear bars yet, but getting close enough for my safety), loaded miles in all kinds of weather & conditions
just my 2¢ worth
