mate after you cinvert the cost of that to aussie dollar then add more for postage it would cost about $90 way better of to go to oz50 and get the kitaco shock. cheap as and from what I've heard there a good shock
I'm not to familiar with the stock crf50 but I did notice that this shock has no spring preload adjustment at all and no adjustment for comp. or rebound so basically there are way better shocks on the market for a pretty good price but you never know it may be stiffer than stock depending on the spring rate. It does look like a very basic shock to me though . If you already bought it just put it on and see how you go thats part of the fun.
