I have a basically brand new (tried it once on my custom gauge setup) speedohealer that fits most hondas. This will correct the very optimistic vtr speedo. It plugs in-line so no cutting/splicing needed; true plug and play. This is a newer model that also has a cool top speed check. From their website:

- SHv3.0-EXT: control unit with remote button
The remote button makes it possible to recall and reset the Top Speed Memory while riding.
You can mount the remote button at the dashboard while the unit is placed out of view, e.g. under the seat. The screw-in terminal even allows you to simply change the remote button per your liking.

- Honda-I plug-n-go kit: Fits ALL Honda motorcycles with electronic speedometer, such as:
CBR600F3, CBR600F4, CBR600F4i, CBR600FS, CBR600RR (2004 and earlier), CBR900RR Fireblade, CBR929RR, CBR954RR, CBR1100XX Blackbird, X11, CB600F (2003-2006), 599, CB900F Hornet, 919, CB1300, CBF250, CBF500, CBF600, GoldWing GL1800, VFR750, VFR800 (2006 and earlier), VTR1000F FireStorm, VTR1000 SP-1, SP-2, RC51, ST1300, XL1000 Varadero (2004 and earlier), VT, VTX1800 (2003 and earlier), etc..


Very easy to setup and use and comes with everything including detailed instructions. I paid over $100.

$75 shipped to conus. Paypal preferred.

Thanks for looking.
