Not used the r1r, but the RE001 aren't exactly a performance tyre, they are a street tyre that is good value for money and you'll see 40k out of them. Don't confuse the RE001 with the RE11/RE01R. The R1R are more a track tyre, unsure of expected life but won't be as much as the RE001, but they will have more grip than the RE001. ive got r1r's on now the front's are pretty low now. have done about 25-30,000kms plus 3 track days. i was real happy with them just seeing what other options there were...
