I think the huge difference is that you're dealing with a very top-heavy bike whose engine has an awful lot of, shall we say, "personality", especially in the upper revs. Oh, and it's not one you can just drop the clutch on and it'll take off. Takes more finesse.
An 1800cc twin, on the other hand, has a MUCH lower center of gravity, lower seat height than yours, likely weighs a lot less overall, and doesn't become a snarling beast at higher revs.
And it takes comparatively little finesse to launch it. Just drop the clutch. In pretty much any gear. <g>
