Streetfighter design - What makes 'em look good?

Make a side-on picture of your bike and draw a rectangle around the edges of the wheels and the top of the tank. Draw lines over every major edge in the frame/bodywork.

Now answer these questions for yourself...
1.) Is the height of the seathump on the same level as the fueltank?
2.) Is the bottom subframe rail in line with the bottom of the seat unit?
3.) Do frame beams running close to the engine run parallel to the cooling fins (especially important on Harris/Spondon-like frames)?
4.) Are all lines about parallel or meet at the same "vanishing point"?
6.) Doesn't your headlight fairing protude over the top of the tank too much (most common mistake).?
7.) Does the angle of your exhaust match the bottom of the seat unit (mine doesn't that's why I used a picture from the other side ;-)

Congratulations mate... your bike looks drop dead gorgeous! ;-)

A few notes on the side...

This is about the classical nose-down/arse-up design, V-Max's and Ducati Monsters may look good too but they concentrate around the "big engine with some bits stuck on"-theme, or the Harley "look what I've got hangin' between me legs"chopper-look.

Keeping a lot of air visible around the subframe area psychologically moves the weight of the bike forward. Covering all the gaps with plates ruins the effect.
