F800s

Test rode one at Vines last month and didn't like either the engine sounding like a bag of bolts nor the belt drive - enough to put me off what I thought would be a great replacement for my 1100s as I mainly commute now.

Sure enough pulled up next to a new one on Friday at Vauxhall - asked new owner whether he liked it and the answer was no. Same reasons especially transmission lash around town from the belt.

Anybody else had a go?

I did try the 1200s as well - delightful but wrong direction for my biking needs unfortunately.

The transmission 'lash' won't be from the belt. If a belt is that loose it'll snap (they have to be run 'tensioned'). There is a little bit of looseness in the transmission somewhere I'd agree.

I personally loved the 800S on the 2 occasions I've ridden it. Slightly buzzy (not as bad as the 1100 though) but nippy enough and fun to ride. I'd have had one if it wasn't so titchy - and I'm a bit un-titchy.

I quite liked it - it's a parallel twin so there's going to be some buzz whatever you do.

handled well.

ABS should be removed and steamrollered though.

I know what you mean about the noise! Was quite nice to ride but sounded like a bag of nails particularly when travelling without earplugs.

had a spin on one yesterday. Ditto the engine /clutch noise (bit like an old f650). Surprisingly quick at the top end with a good spread of power and seemed to run on a sniff of petrol. Reminded me a lot of my CB500 with a big engine (that's a compliment) . What ruined it for me was the transmission (backlash) . I wonder have they any cures for that?

I've been lurking on the F800 Riders forum, where folk have been saying there's a re-call for the bike; apparently the box's selector drum as been victim to some 'manufacturing quality issues' and bikes will be fixed by BMW.

Those who have had the their machines sorted state they feel like a new bike, no backlash and a much quieter motor to boot.

Gromit, interesting link. At least it wasn't me then , it's been decades since I had to actually think about changing gear smoothly

My my, BMW are getting creative these days!

Unless gearboxes have changed radically in terms of which bits go across&back and round&round then a selector drum has no connection with backlash at all.

Maybe they're changing something else instead.

Must admit, even to my somewhat dim-witted mechanical knowledge, it did seem rather odd. In which case, what the H are they doing with them?

There's play in the transmission on the F8 that's for sure. Won't be the belt as with that amount of slop, it'd last about 200 yards before snapping.

I reckon it's the flanganated dufflebucket.

It will be the clutch or the clutch basket that they change or both

But I thought Rotax made the clutch...not Yamaha?

Could be the answer - the clutch teeth being too small for the basket's slots. Similar problem used to happen on FZR1000 Exups (like mine did). On those the swarf from the rapidly-expiring basket would get into the oilways and starve the motor's top end. Then the small ends would fail through lack of lubrication resulting in a snapped rod.

Don't ask me how I know this.

It was spectacular though
