Bike Aerodynamics - Advice

So I've been riding my Z750 a few months now and one thing that's bugging me a bit is the amount of wind u get in your face @ 90+, I didn't realise just how uncomfortable it is on a naked bike.

So my first thoughts are screens for wind deflection but there are hardly any options for the Z750 really and I don't want to be drilling fairings and detracting from market value as I will prob move it on in a year when I can afford to insure a 600 sports, which got me thinking.

Are there any bikes out there similar to your R6's GSXR's that are a decent insurance group but have double bubble screens upfront, whilst retaining that sporty look. I'd be in no rush but I could put the Z up for sale and look at other models of bike...

I think the Z is group 12 so something along those lines would be great. Any recommendations?

Try looking at GSXR750s or the 750 variants of the sports...seem quite cheap to insure.

Even some litre twin sports are cheap (TL1000R)

The only one I've found so far is the GSX 650F, @ group 12 that would be an option. Looks like it comes with the GSXR front end!!

Give a Ducati 750ss a quote, you'll be pleasantly surprised Thumbs Up

FZR600/FZR600R

I've got the R and I'm pretty sure I can get a double bubble screen if I wanted to but the wind at 90/100 isn't that bad anyway.

Also the FZR750 & 1000 if you wanted a bigger engine. These will all be 90s/late 80s bikes though.

What about a Z750S?
FZ6S/FZ8S?
XJ6S?
F800ST?
Z1000SX?

You can fit a double-bubble/flip/touring screen to pretty much any bike with a standard screen.

Mmm, I see your point. All I really saw of Tefs is "don't go fast" and "slow down"

I know its majorly different, ridden the GSXR and a Bandit on motorways/duals at around 100, the GSXR felt far comfier, a lot less pressure and did feel slightly less obvious you were doing a ton.

The bandit was tearing me off the seat Laughing

Half my problem could be that I'm riding with sportsbikes I guess, top end poppers. Think I might just bare with it for now, it's not anything that's seriously bothering me, just been niggling that's all. Like you say it's not about playing catch up, I'm happy to be the capitan slow of the group anyway Very Happy

You canny make a silk purse out of a sow's ear.

Trying to improve aerodynamics after the fact is closing the door after the horse has bolted.

For the best wind protection you need a touring bike with a big screen.
There are 'Sport-Tourers' but they offer marginal protection for neck and head in the average male rider.

Simple rule, if you stick your head up you get it shot off.

Fitting an after-market double bubble etc. is only a token effort at improving what is probably terrible in the first place and any benefit is usually just the poor sod who paid over a hundred beer tokens for a piece of plastic that offers not much more than the OEM piece of plastic justifying his 'investment'.

They only afford this marginal improvement if you can keep your chin on the tank for ages.

I am one who has paid dearly for the tosh MRA et al claim solves all sorts of troubles.
The trouble is I don't know of anyone who will let you try and return if not satisfied. I can bet that market would be crippled if such a scheme existed.

Most folk like how an after-market screen 'looks' so can swallow the loss in claimed effects.

I sold my ZX9R for this very reason. I'm fine with that, it's just it catches you out. Then all of a sudden, 70/80mph is very boring. I'm using it on the road - I don't want to be bored at those speeds.

It would effortlessly do 120+ everywhere. The hornet keeps my speed down. Now 70mph is fine again.

Agreed for distance no fairing can be a pain. I'm off for 2500 miles round europe in 8 weeks, I'll just fit a little fly screen.

No, I'll be riding it. I'll just have a beefcake neck upon my return.

Pfft, I juggle work and evening classes.

Stop abusing me and take that S1 on the track...
