There is NFW a TBA is going to "spank" a 1200 Sportster assuming both have the standard stage one intake/exhaust mods.



I emphatically agree 100% However, with 'normal' mods on the intake and exhaust, a TBA will give a good chase and depending on the throttle-man (aka the rider ), they might be able to pass them.

but these claims of "spanking" are ridiculous.



Exactly

Quote:

I'll even say that a stage one 883 with the stock sprocket will run at least dead even with the TBA up to around 90 mph



100% agree

She ran out of juice at about 90 but I could coax her up to 110 if I didn't have to big of a breakfast.



oops!

...and btw, I have 'spanked' both but I attribute that to driving experience.....

And lately to the big bore....
