Yes, the 1100. On the right side, where the oil filler cap is, if you look down there you will see a little window with a screw head in the center of the glass. Its a little hard to see, but its there. The best way is to have the bike on the center stand, have someone start the engine for you, and with as flash lite pointed to the window, have that person stop the engine, you will see the oil settle down and be able to see where the level is in the glass. A bit primative, but that's the best way. The 1200's got lucky and have a dip stick.
I use Motul 10w40. Check with your local dealer.

The 1100 has what is refered to as a wet clutch. The same oil that is used for the motor oil is used for the transmission. Because of this it is very important to use oil that is labeled "Wet Clutch Compatable". You can get this through your Honda dealer or motorcycle shop.
What model?
You will have to start with the basic things. Do you have fuel ? and do you have spark ? check these 2 things first.
4.8 us quarts, but check the dipstick when your done, attached to the oil filler cap
Good idea to check the battery. Might need to be charged, or changed.
There are many places to buy Honda motorcycles. One of the options is to visit a Honda dealership and inquire if they have any Honda CBR 929s in stock. Another option is to check the motorcycle section of Auto Trader.
