Sensible commutermoto idea

[Gazdaman]

My question is, why hasn't anyone made the following...

A sexy supermoto chassis, similar in looks to say a WR400, undoubtedly sexy.

But with an IL4 motor, say out of a Bandit or similar, simple motor, oil cooled, still makes 80bhp, so the same or more than your average smoto.

But you could scream around, but it'd be smooooooth and therefore ridable all day without your fingers going brittle and snapping off. And decent service intervals.

I think it's a great idea, I'd buy one. In fact, I might go buy a WR400, a bandit and a welder.

Can only imagine it comes down to an inline 4 engine being a fair bit bigger. Would be cool though.

[Gazdaman]

I could be persuaded by a parrallel or v-twin I suppose. A bandit tank section isn't all that wide, I suppose it would need a fair bit of work to make the tank and side panels wide enough to make it all fit.

But I can't see any major problems, I just don't understand why people persevere with single cylinders in supermoto reps. They're impractical for people who just wanna pose on the road.

Well apart from the engine being very wide, I think you'd have a problem with the exhaust routing and still keeping the looks of a supermoto?

SVX is a v-twin. Engine would stick out the side, anyway/
How about a highland - 950cc 85hp twin, supermoto form is one of the options. Weight claimed at 166kg.

I've wondered about this before - but if you look at the weight of a sports bike, very little is in the frame (I almost chucked the R6 frame up in the air when I first went to pick it up after stripping, as it weighed so little!)

An inline four in a trail bike chassis featured in streetfighters many moons ago.
Something like an SV650 engine would make the most sense I reckon, but you are starting to pile the pounds on and not sure how well all the components in the enduro frame would take it.
However, not sure how well the frames would fit in a bigger v-twin. A wide engine, however, I think might be a bit annoying on a wide bike.
There's the BMWF650/ F800 range which are kinda similar, but quite hefty for what you're thinking.

Oh and the KTM690 apparantly makes around 60hp as stock, a little more with a can on; so not too far off what you're looking for!

Oh and I was going to say you have a strange idea of sexy (cobbled together for functionality with some stickers chucked on), until I remembered what your Corsa looked liked .

What I meant for the pedants (also known as 'G') is that it's torque is more instantly accessible!

Edit: but we agree buy a bandit or a Hornet and save lots of time and money. Or take the fairings off a sportsbike and fit flat bars

[Gazdaman]

Logistically it would be fitting the suspension from a moto to a road bike, but it wont look like a Motard.

I remember Stinkwheel posting about someone who made a motard version out of his SV650.

Gonna read now.

[Gazdaman]

Yeah that's not bad, along the right lines, but I like the look of the stretched swingarms on motards, and the high rise arse plastics.

I'm getting really tempted to try it to a naked Bandit now.

You're right, they should make inline four supermoto bikes. Please make the bandit-supermoto hybrid...

Downgear a ZX6R to the same as a 600cc supermoto and you'll find that torque is much more 'instantly accessible' on the sports bike, I bet. A modern sports bike with a lower CoG and more weight will wheelie at pretty much any point in first gear and not too far off in second. First gear is equivalent to maybe 4th on a recent big cc supermoto, with second definitely 5th or 6th. My KTM won't lift the front with nearly the ease that the sports bike will.

Generally bikes intended to be supermotos have shorter swingarms - longer just for an 18" wheel with big knobs on.

I have to say that, yet again, I am disappointed that it's come down to the tarty side of things again .
So... stick some WR fairings and stickers on the fireblade and you're sorted .
Incidentally, have a look for beach racers... think they often use big bikes done up for off-road use as they need the extra power for the long straights (forget the categories, but we're not talking Weston' obviously.

Oh and if I ever get around to getting it officially serviced, blag a go on my 690 sometime Gaz. It's still not amazing, but handled cruising at 80-90mph and even managed a GPS 108mph with a pillion and big panniers. I upgeared it to do a theoretical 125mph in top which made the sustained moderate speed cruising a bit more comfortable.

[Gazdaman]

Sounds good G.

I rode a KTM 950 SM once, that was nice, but it doesn't look like one of those focussed motard type super motos.

A V-twin is an improvement over the single, but I want a loud screamy IL4.

I'm getting ever more tempted to do it, but it's just got "expensive" written all over it. I'll have to buy a semi decent Bandit, maybe one with crash damage. Then get an entire front end, swing arm and shock from a supermoto, oh and wheels. Then the entire bodywork including lights.

I'd pretty much have to buy both bikes.

Still, tempted.

Gaz

[Gazdaman]

Yes it's a crap photoshop, but this is what I want.

And I sorta agree it'd be easier to start with a Bandit than a smoto.
Then I can sell any bits than are left over, like bandit front and rear end, shock and wheels, then the smoto frame, and engine.

Gaz

Bandit's aren't that light/small in the first place, so were it me I'd go for a sports bike; but it's your aethetic dream.

Most of the longer swingarms you're considering will be too narrow to take wide tyres as they're longer because they're made for enduro tyres .
If you get a swingarm from a supermoto it will be of the shorter type generally.

On a different purpose, I have considered trying to longer travel suspension on the 675 (nice narrow frame) to make a moderately light weight adventure-touring bike.

Have you seen the 950/990 enduro? Not sure what the supermoto (as there's about 5 different bikes all quite similar) looks like, but the enduro one does look quite, well, 'enduro'.

[Gazdaman]

I'm not really fussed what bike I start with, just need something cheapish, reliable ish, and the power of a bandit is quite a plus point, if I used a sportsbike I could be pushing 100bhp and it'd be a complete monster.

I would want a proper smoto swing arm, just like is pictured above. But obviously must take a decent size sportsbike wheel and therefore tyre.

It would still be an expensive project, I'd need to buy a supermoto donor bike I guess, to get the shock, the plastics, the front end the swing arm and the wheels and brakes. To get a decent one to take the weight of the Bandit I'd be looking at a complete minimum of £1500+.

Then probably £1000 for the sportsbike. But could maybe recover £800 max from selling parts.

I'm sorely tempted. Only bad bit is if I bought a nice donor supermoto I'd just ride that and fucking love it, and stop moaning about it being a single.

So I'd have to find a crusty one, or one without an engine or something.

Gaz

[G]

I suspect it could get very expensive. Remember you're going to have to at least re-spring the suspension to account for the extra weight, possibly re-valve. Have to fabricate up quite a lot of stuff too that will need to be pretty accurate to stop the bike tearing it's self up.

I can't quite tell, but most probably the swingarm pictured at the top is not a supermoto swingarm, but an enduro swingarm.
As previously mentioned, supermoto swingarms tend to be a bit shorter, and in some cases wider to account for the tyre. However the positioning of the engine (front sprocket) in relation to the rear sprocket would also be 'interesting' depending on the configuration you had.
Also, these swingarms may not be made to take longtitudanl forces that you could put through them.

All that extra weight may mean a single front disc starts to have 'issues' too if you want serious stopping power to be used regularly.
Then there's the cooling, as the singles tend to have smaller rads that are to some degree protected.

Much better:

Just get a speaker that plays an inline four sound and play with the FI to adjust the mixture at different revs .

I believe this is what your looking for.

Road tyres and job's a good un.

stinkwheel Well I just had my hands up a pigs fanny. Which makes your concerns pale into insignificance.

[KevTM]

Road tyres and it's just an R1 (almost).

[Gazdaman]

Along the right lines, but I want more enduro bodywork on it. If I put road tyres on that it'd just be an R1 with silly forks again.

I wonder if I could just use a normal Bandit rear end, just jack it up like fuck with a longer shock or dog bones. Would make it a lot of a simpler project too.

Jack up the rear like fuck, fit enduro plastics, fit supermoto front end, bam. Although that's not much of a project. That's just a crap Bandit streetfighter.

Oh yeah, spoked wheels are a must for the true image.

[Gazdaman]

Hmm, I'll do some thinking and some eBaying. But I think this project might happen.
