I'm in the process of fitting a set of T3 Daytona wheels to my TBird (which has a TBS front end and TBS rear wheel). My reason for changing the wheels is that I'm fed up with the hassle of fixing punctures on tubed tyres. It's all work in progress at the moment as my wheels are off to be powercoated so don't assume anything I am about to write is correct!
The rear wheel is a straightforward bolt up as the swing arm dimensions are the same across the T3 range. I did measure all the components/spacers for the rear wheel, but since they are the same as the TBS, I didn't note them down. In addition to a Daytona/Trophy/Sprint wheel, you'll need the early 'above the disk' type caliper and associated mounting hardware - such as caliper mounting, torque arm and naturally, the smaller brake disk to go with the wheel. I've tried a Daytona wheel fitted with a 180 x 55 tyre and there is sufficient chain clearance for that. I'm planning to go with a 170 x 60 though as that is more than enough for the TBird in my view.
The front wheel needs more work. The nominal sizes to which I've been working for the TBS front wheel (from right to left as seen when sitting on the bike) are: 35mm speedo drive + 12mm wheel bearing + 65mm inner spacer + 12mm wheel bearing + 21mm LHS spacer = 145mm between the forks.
The Daytona wheel uses the same wheel bearings, the only difference seems to be the length of the internal wheel spacer. The TBird's is 7mm shorter than the Daytona/Trophy etc. The Daytona inner spacer is 72mm so I've trimmed 7mm from the TBS LHS spacer and everything should line up. I've attached a pic of the front spacer with 7mm trimmed from it.
As far as I can work out from the part numbers, the 21mm LHS spacer is common across the whole T3 range, so the Daytonas etc. must have had different width on the triple clamps. What I haven't figured out yet is that the TBS calipers line up OK with the Daytona disks - the disk spacing on the Daytona wheel is exactly the same as the TBird Sport wheel at 140mm measured across the disk surfaces. I know the calipers themselves are different, but there must also be some differences on the Daytona fork leg caliper mounting points too. Although both the TBS and Daytona front wheels are nominally the same 17 x 3.5 size, the Daytona wheel is actually a touch narrower across the rim. Presumably, this will produce a slightly more curved profile to the tyre and may make the bike more keen to change direction?
The TBS caliper lower mounting bolts are fractionally too long to clear the rivets of the Daytona's floating type disks, but these bolts can be trimmed accordingly. Alternatively, the early type non-floating disks originally fitted to the Trophy range would probably be a straight fit to the TBS calipers.
Hope this helps - I'll post more when I've done a bit more work.
