Deluxe front is longer than Classic. You will have to cut off the fork shafts a few Millimeters. Also, don't forget the rest of the costs, as it won't be cheap.
Here is a vague list of components you will be needing:
- Disk Plate
- Caliper (Hydraulic Operated - NOT the wire operated)
- Master Cylinder
- Brake Liver along-with the complete asymbly (to fit the hydraulic system)
- One (left) fork leg with Caliper Mounting (left fork leg, to fit the disk brake on left side. Rear brake is on right side. It'll balance the bike on high speed braking)
- 2.75-18 Tyre of Dexlue, along with compatible Wheel/Rim (It'll add to stability of disk brake).
Basically, its well above 15k worth of expenses. Tension alag.
If i were you, i won't waste my time on it, unless there is too much of free time
