V85 new engine design?

[M0T0Geezer]

Thanks to Peter949 for posting a link to the awsome V85 brochure.  Old Moto-G still has something to say to the ricers.

Now, imagine a new "Compact Norge" 850cc with the new, lighter-weight, rear-drive and 80hp V85 motor.

That really gets my shaft turning...

You mean a new B850 Breva.

Why not an LM version? I know there are others feeling the same way. Lower the bike a few inches, add appropriate suspension (braking) and fairing, plus non-bulky luggage.   
The above changes and a body kit and Zoom! 
Except for a VFR I've not toured on an yclept touring, cruiser, et al. R3~ 

BTW: A typo gives an astronomical seat height. It should read 32.2".

A new "LeMans" should be faster than the last Guzzi sportbike, the Daytona. ( MGS-01 was a track only so no need to shoot for that benchmark)
The LeMans name needs to remain in mothballs until they go to some form of liquid cooling IMO.

It might be a better sport bike but in terms of engine performance the Daytona RS made either 92 or about 102 RWHP, so with 68 it’s not going to be faster.  I suspect they’ll do something less overtly retro than a new Le Mans.

A 850S for those that like retro would be cool...  I think the racer was a little much cafe racer for a lot of people... 

[Turin]

A V85 Monza would be cool !

I'm still not clear on how a valve material change can get that big of a HP bump. I have to wonder what else goes with that change.

The oil filter thing confuses me. With the right tool, removing the cover to swap the filter is a pretty simple task. I can do it faster than changing the oil and filter in my Honda. It is up there with the tube versus tubeless. I've patched a few tube tires on the side of the road. I've plugged a few tubeless tires along the road. I would never base owning a bike on one way or the other.

It also looks better hidden.  Who wants to look at a spin on oil filter?

OK, I am the least mechanical person here but I don't understand that chart.

Shouldn't the torque and hp lines cross 5250 rpm?

Performance measured and featured in the Italian magazine Motociclismo:

I think the big midrange dip is disappointing.



It seems that they have measured 69,6 HP at the wheel which means 76,3 HP at 7700 rpm

My thought would be that as on onroad/offroad bike you would want that crossover at a lower point than a crotch rocket.

This depends entirely on the scaling of the diagram.

[Tusayan]

The 5252 crossover number is true for any dyno test if the torque is in foot-pounds and the power is in horsepower, but in this case the torque is expressed in Newton-Meters, metric units.

Thanks.  Just checked this on the net.  Wow, always learn something here

>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>

On a dyno graph that is in Hp or kW for power, and in Nm for torque, you will not have a crossover point at 5252rpm. You might not have a crossover point at all...

In the metric system power is calculated by the following formula:

P = Torque x 2pi x Rpm/60

P = Power in watt
Torque is in Nm


In the imperial system power is calculated by the following formula:

HP = Torque x RPM ÷ 5252

TORQUE = HP x 5252 ÷ RPM

(the sign ÷ means "divided on" - there is a different use of this symbol internationally. Somewhere it means to subtract and elsewhere it means divided on)

So, in the imperial system you have a constant and that is the number 5252. This means that when you convert the formula to represent either Torque or HP, you will allways have that crossover at 5252, because of that constant in the formula. The 5252 is there as a factor to let you get the torque in lb.ft. Using either kW or Nm you cannot use the constant of 5252 anymore. In fact you don't need a constant to convert the answer to a understandable metric. And since there is no constant in the formula, you won't see a set crossover point as you do in the imperial system.

Thank you everyone for the replies to my post on the V85tt.
Here is a great link that well describes this 'new' engine:

Thanks for this...very informative!!!  I really like this :)..............seems like there are a few typo's? or I'll never ride one as the seat height is 82.5 inches...whoa...I think they meant  more like 32 2/3"....which is till to high for my stubby Italian inseam...:(
lowering options offered?

[Tusayan]

FWIW 82.5 cm is 32.5 inches, so I'd guess that on the number.  I'd like the tall seat option, if it's really going to be available, or would reshape the foam to resemble an R100GS seat.  The basic shape of the seat is similar, so I think that would work.

[Bulldog9]

Also, 100 hp from a 1 litre non-turbo motor is pretty much unobtanium.  To get 35 hp or so from each of two 425cc 2-Valve pushrod, normally aspirated cylinders seems pretty decent to me.   Sheesh, I'm more than happy with the 44 hp from each of my pair of 575cc 2-Valve Norge cylinders. 

'Geezer

Crazy as it sounds, Yamaha is getting 200HP out of its 998cc  LQ inline 4 on their R1...... Kawasaki is getting 197.... @ 13500 rpm, and of course much less torque 83 @ 10000 rpm. Not a real comparison and not my "cupotea" No torque and 13K redlines..... But I would have thought that impossible at one time.

As for the V85 being 'new' does it use any of the same castings, or casings, cranks, c rods, pistons, heads from current small block designs? From what I understood its a fresh paged take on a tried and true design. New crank/journals, bearings, oil pump, pistons, c rods, heads, etc.  Also looks as if the head is precast to eventually go 8V.

[Turin]

I think he meant an air cooled 2 valve per cylinder motor.   Liquid cooling and multiple valves are a totally different ball game.
