Search ebay for Tygon, very happy with those.
+1 to you it was tygon i remember that name
but on a side note.... promotion any good?
Motion pro line on Z1 site comes in ID of 3/16" 1/4" and 5/16".
Those sizes translate into 4.76mm (too small), 6.35mm (too big) and 7.94mm (wayyy too big).
None are the 5.5mm size that your bike needs.
You could probably squeeze the 3/16 line on there, but it's gonna split eventually, exactly when you don't want it to.
Answer is NO those won't work.
