If you tend to fumble dipstick extraction, just drop a 5/8" or 16mm deep socket over it. Makes a nice handle with zero mods to your bike and at no cost as long as you have the socket.
It's an overpriced solution to a problem I don't have. No thanks.I purchased and installed Traxxion's dip stick extension couple days ago. Works well, EZ to install with some included epoxy paste, looks like it came with the bike.
Yes, cost is more than $5 ... but, well made, and Max took some time to do the R&D on this addition. I'm happy with it.
Check it out on Traxxion's web site.
