Here is the list of parts I purchased to complete the job;
- 40mm Rightside Brembo Caliper #20.5165.68 ( I bought mine used off ebay; you can see the models that have them OEM at the link below.)
- Brembo brake pads #107.4426.45
- 320mm Aprilia Mana 850 front right brake disc (See below link #51 for multiple types of 320 mm discs, but also understand there is more available that isn't on the list. Just verify the caliper has an outer diameter of 320 mm an inner Diameter of 64 mm, a disc thickness of about 5 mm, obviously 6 holes sized 8.4 mm and a hole Circumference 80 mm.)
- Motolanna 10mm spacer and mounting bracket for the 40mm Brembo P4 brake caliper
- Dorman M8-1.25 x 35mm hex bolts #981-435D or similar type from your hardware store. This will be needed to make up the difference created by the spacer for mounting the disc to the hub; Need 6 bolts for the wheel hub.
- Hillman M10-1.50 x 30mm Allen bolts #43116 or similar type from your hardware store. This is the correct size to mount the caliper to the bracket and fork. The yamaha stock bolts have different thread pattern and the Brembo bolts were a little too long. You will need 4 of these bolts.
- Mikesxs spoke kit #19-0067
- Takasago 18" / WM3 / 2.15" or similar size REAR rim. I opted for a cheaper brand than the excel rim, but it looks quality to me. Also the WM3 type rim matched my actual rear rim style so I would recommend you research this before you purchase a rim. I only saw the gutter style rims on Mikesxs. Also I am not sure if the 2.5" wide rims will fit, because the caliper was close to the spokes on the 2.15” rim. The spoke kit from mikes is for a rear rim to a front hub so make sure your purchase a rear rim.
Shouldn't have to mention it, but you will need these following parts;
- A 18" FRONT tire I opted the size 100/90-18 and think it looks good and doesn't throw off the speed-o-meter judging off one of those digital radar speed checkers I drove by on the side of the road.
- A 18" Tire tube
- A 18' rim strip
- Brake fluid
- wheel bearing/brake grease
- wheel balancing weights
These parts may not be needed but I had these fitted before this project.
- Braided brake line (might as well) you can pick your poison, but I used some chinese brand and I have had them for a while now since before this set up with no issues. I have shorter handle bars so I have a 39 cm for the top line and I can't remember the length for the lower line. I want to say it was 50 cm, but they have plenty of sizes available so just make sure it has a little slack.
- Master cylinder (why not) most Ducati single disk run a 13mm and if your going to do a dual disk then 16 mm is a good size.
I was able to true my rim and spokes myself, but if it wasn't so expensive to do in Hawaii ($125) I would have paid someone to do it. Also paying someone to mount tire and balancing tire will save you some headache and keep you from scratching the new rims. If you do spoke your own rim make sure you number all the spokes on both sides. I started from the valve stem hole and number with the rotation direction of the wheel. I kept the spokes for the inside and outside separate and it made it easy knowing which was an odd number spoke or an even number spoke. Also I didn’t take off all the spokes before installing the new ones so I didn’t forget how they were installed. You will need to remove the rotor disc or it will be in the way of getting the spokes on and off.
Bleeding the brakes was so much easier with a kit I purchased from O'rielly's the brand is Performance Tool #W80625. I will never go back to the old 20 oz plastic coke bottle and tube, but you could probably make something that doesn't create such a mess.
Also I opted to put a washer between the dust cover and fork leg on the right side to ensure that the spokes didn't get too close to the brake caliper once the nut was torqued down to hold on the wheel.
The bike rides smoother and is easier to lean into a curb now with the wider 18" tire in the front. Also the brakes perform way better than the stock caliper set up. Feel free to ask me any questions on here so we can share with the rest of the group.
