Can we get a final answer on speedometer sensor?

[RDAGlock]

Hello fellas! Long time rider, and Just picked up a new 2024 Busa… and educating myself best I can on this beast, specifically the Gen3. I think I’ve read the last 40 pages or so of the gen 3 forum. LOL

One thing I’m finding contradicting information on is where the speedometer gets its reading from… front wheel or back wheel. Is there an official answer on this? I swapped out the stock 43 tooth rear sprocket for a 45 tooth, and wondering if that is going to read a higher speed (and put artificial miles on the bike) than is accurate. That said, If it gets the reading from the front wheel, than all is good. I see that there is a rear wheel speed sensor … but wondering if that’s just for traction control electronics.

Thanks in advance gentlemen!

Front for speed, rear for traction control. Watch your speedo when you do a long wheelie. Also, you'll never need a speedo healer. Older bikes had the speedo on the output shaft so it didn't take sprocket changes into consideration.

Good to know, because my next rear tyre will be a 55 profile, and I had to adjust the gearing on my GSXR 1000 when I changed profiles.

Does this hold true for the GEN2 busa's also or the GEN2 busa's need a speedo healer after sprocket change.

When I had a 200/55 rear tire on, the speedo was actually a tad bit more accurate.

Gen2 Busa will need a speedo healer for sprocket changes. They take their speed off of the output shaft of the transmission.
