Will a honda cbr300f be enough for me to ride to and from work?

I'm looking into buying my first street bike. I'm wondering will a cbr300f be enough to take me to and from work. My work is 35 miles from my home. I weight about 175 and that is without protective gear. I want to know before I get my hopes up if the 300f will allow me to ride at 70 or 80 miles per hour and still allow me to accelerate to pass vehicles if needed.

Is a 1982 Honda cb450 Nighthawk a good bike?

I'm looking at a 1982 Honda CB450SC Nighthawk. This is my first bike. There are 26K miles on this bike and the dealer wants $1375 for it. Kelley Blue Book said this bike is worth $1175. I ran a vehicle history report and found nothing wrong. Should I buy it? How much should I pay?

Is my motorcycle routine bad for my bike?

My driveway is on a fair incline so (as far as I'm aware) I have to ride up and I try and get a bit of a left turn on the bike, then I put it in first or already have it in first gear then put the sidestand down which kills the engine.

I have a Honda CBF125 2014, and the sidestand is designed to kill the engine when deployed.

Then when I want to ride the bike I sit on it, put the sidestand up while holding the front brake then I hold the clutch in fully and slowly release the brake to roll backwards onto the road then start the ignition with the clutch still in then drive away. This also means that I don't give the bike a chance to idle with the engine on but since it is such a modern bike and not winter yet I don't feel the need to. The bike's rev limiter instantly goes to the right place and stays there and the engine sounds the same at 2 seconds than at 10 seconds, and doesn't appear to need 'warming up'.

Is it bad to "stall/kill" the engine in first gear every day and leave the bike on an incline in gear every day?

Added (1). *rev counter, not limiter

If you build a motor trike in the UK what do you need to do to get it road legal?

I have always wanted to build my own road legal vehicle. I have thought of building a motor trike from motorcycle and car parts and building my own chassis. I have also considered converting a 1980s Honda 125 into a trike.

I know all about making sure its road worthy etc, sound chassis, brakes, suspension etc.

But once built how do you get it registered and get a vehicle identification number as the chassis is newly built? Is the process expensive? What order do the legal things need to be done in, such as VOSA, DVLA etc?

Is insurance considerably more expensive in a home built vehicle?

In the market for a sport bike?

Should I go with a 2008 Honda cbr or a 2011 gsxr 600. I'm looking for a bike with a comfortable feel and a daily
Commuter when I do t want to drive to work. Also speed is a plus but I'm not looking to race somebody everyday when they pull up next to me. I've heard Hondas are reliable and that gsxr 600 are the best and faster.
08 cbr $6700
11 gsxr $8700

What is the best headlight for the money for a 2006 Honda crf150f?

I would like to get a headlight for my motorcycle so I can ride the trails when the sun isn't completely out so I can avoid the heat. As I said I have a Honda crf 150 f that is electric start. I would like to have a dependable, good quality headlight. My price range is about 100-200$ depending on the light. I have seen some that also come with a tail light, and that is okay as well.
