Help Converting?

KTM wheels and Bergs are the same.....I am ordering KTM wheelset....the part numbers are at work so I cannot quote.... KTM's are cheaper
I'm getting a 3.5 by 16.5 front and a 5 " by 17 " rear in black.... $ 800.00 for both no cush drive (now I will have two sets).....450 SMR's and 525 SMR's are identical, Behr is the builder.... (stock sizes are 3.5 and 5 inch by 17") not the lightest out there but well made and good enough for me...... If you go full tilt on talon hubs or excel rims with Buch. spokes you will be in the $ 1200.00 range with the proper spacers......If I remember correctly the MX rotor will bolt up......KTM and Berg offer 310 mm brake kits as well 320 mm, I prefer the 310 mm set up as its easier for the 16.5 " to clear when swapping from my dry set up to rain set up....
gearing for kart track will be 14/46 or 14/48...last note, you will require sintered pads the stock pads won't last long at least If you are on the track....the MX front brake will get very hot If you are in the twisties and you WILL get brake fade....hope that helps..... :wink:
