this is a really good product, bought for my new hondaxr125L-3
length is good, enough to go through my wheel and frame so the bike can't be moved, would also be enough to chain the frasme to anything you want or indeed the wheel. light enough to put in your rucksack, it goes in mine on my 30 mile ride to school some days i dont get the bus. also site happily on my rack with the addition of a small tight net. doesnt make too much noise when its on the rack.
ONLY ONE CRITISISEM: it says it can double up as a disk lock. probably can on some models, and sort of can on mine, but the lock is far too fat to go through any cooling holes in either my honda or my moped. so if your holes are large then it will work, however i have to put it through the back of the disk, not the cooling holes.
excelent product, definately buy !
