Yes Ray , there is a offset listed in the Manual , what i have generally found when lacing wheels is that they usually "fall into place" and ends up if you snug it down correctly at what "spec" should be , i have rarely had to "adjust" the wheel to get it to spec , in the case of the 250R , the Front is 28.0mm +/- 1.0 or 1.10in +/-0.04 , the Rear is 48.75 +/- 1.00 or 1.919in +/- 0.039 , measured from the hub to rim edge on the sprocket side , so when measured
Rear: Left outside edge of the hub (Sprocket mounting surface) to the leftmost outside edge of the rim should be 48.75mm +/- 1.0mm.
Front: Right outside edge of the hub (Brake Rotor mounting surface) to the rightmost outside edge of the rim should 28.0mm +/- 1.0mm.
Make sense ??
On a related note , i just laced a 2016 Husky 350 front rim for a friend that had a altercation with another bike off a jump , it totalled the rim , it could have passed for a capital letter D , so he gave me the new rim and a new set of spokes and his hub , as he had already cut the spokes to disassemble the wheel before i got to it , so i got a bag of spokes , a wheel and a hub and was on my own with nothing to reference it to , anyway , i laced it up and took it to him the next day , i actually had it done in just about a hour but i had to install a new tube and front tire as well , I told him to tell me if there was any alignment issues with the brake , ... he had no issues and the wheel was right where it was supposed to be
