I love the Bridgestone 190/650r17, I drive a GSXR1000 L1 daily. And these are the only tires I will run!
As soon as my factory battlax tires wore down, I slapped a set of 190/650/17's medium rear, and 120/600r17 front medium.
People dont usually run slicks on the street, but i was facinated with the shape of the tire. Its much better than a 55. They warm up very quick, and they do good with heat cycles.
After I pull out of my driveway, and a few mild mannered miles later, they are ready for maximum lean. I have not had any scary times, or sliding around.
Much better than a factory 190/50 with a flat like profile. And much more forgiving than Dunlop GP-A's..
They have excellent corner entry. The bike leans easily with minimal effort.
I do not make H2, or H2R power, but with a Yoshi ecu, and a Yoshi 0.55mm thinner head gasket, and cotters. I make 182RWHP, im still running stock dual exhaust.. And these tires are just sweet!
It makes for a fun trip to work.
You can buy them online, I may try the 200/655r17 next. It will increase most bikes ride height drastically. So, I needed to tweak suspension for switching to slicks, and the much taller tire to.
Its a drastic difference from 190/50 to 190/65
