Nothing.
What a beast. I hadn't ridden since a bad wreck 18 years ago, so the first ride felt like a run on the back of the minotaur. Nobody needs this much motorcycle, but everybody dreams of it.
The bike takes off like the space shuttle with only a couple of negligible flat spots in acceleration. Gears 1 to 2 mash a little noisy, but are starting to settle down.
The bike is not for small or short drivers, it feels heavy at a stop, but balances perfectly at low speed and beyond.
The bars could be a little longer and the seat feels like plywood after 10 miles. I replaced mine with a custom with gel insert.
This bike can put you in bikers heaven, literally and/or euphemistically depending on how well you ride. Be careful, enjoy and be careful.
5'3" and I love my VTX 1800 C. Height is negligible on this bike.
