Re: Lightened Flywheel - what's involved?
mmmmm no idea!!
Looking at the manual, I need a flywheel holding tool and puller -after the nightmare with removing the flywheel on my Multistrada, can anyone confirm where to get these from/what brand so I get the correct ones please?

Making up since 2007, sometimes it's true...Honest...

M22x 1.5 RH thread
A made for use remover is just a few pounds.

but any M22 x 1.5 right hand thread bolt will work... There are cars and trucks that uses that size for drain plugs ....they work as well.

Re: Lightened Flywheel - what's involved?
Slightly off-topic but what is the reason NOT to have the lightest possible flywheel on a race bike? Flywheel weight (rotational inertia) smooths the engine at low revs and allows a lower idle speed. Neither of which are needed on a race bike. It also slows lateral transitions. What am I missing?

Re: Lightened Flywheel - what's involved?
IMHO, there is no reason not to have the lightest version on a street ridden VTR.. Not a single person actually using one my lightest one has had any complaints or gone back to a heaver one.KermitLeFrog wrote: ↑Tue Nov 27, 2018 5:02 pm Slightly off-topic but what is the reason NOT to have the lightest possible flywheel on a race bike?

Re: Lightened Flywheel - what's involved?
E.Marquez I'll take your advice - I know why they have flywheels but I don't know the true effect on riding, would it be more likely to lock the rear on changing down and not matching engine speed?

Re: Lightened Flywheel - what's involved?
Mines in bits for gearbox brgs. so I used an Iveco truck stud to push off and a windy gun to undo the bolt. In Fleet if you have no-one closer.
Re: Lightened Flywheel - what's involved?
Thanks Commando, how do you intend to tighten - I was told definitely not to use a rattle gun to put my Multi flywheel on - I assumed the VTR would be the same?
Re: Lightened Flywheel - what's involved?
If you have a torch and vice, an easy way is go buy a cheap open end spanner, heat the handle part near the open end cherry red and bend a Z shape in it. Like that only for the VTR you would use the open end
Or
If you have a welder and such, its pretty easy to weld a tool up from some flat stock or plate and some tube or bar. If it is a non Hex shape like the VTR is, I cut um out with a plasma torch these days if I don't already have one that fits . If its a hex shaped part of the flywheel, I still go get a cheap spanner and bend it up to fit...quick and easy.
I would not recommend using a strap wrench, chain wrench or even a strap type holding tool made for flywheels on the OD of the flywheel if the flywheel has been lightened.
The steel around the magnets on a lightened flywheel is very thin after the work and easily deformed

Re: Lightened Flywheel - what's involved?
Correct, while some do it anyway and the earth did not stop spinning, more than a few have broken the hardened washer, overtightened the bolt, under tightened the bolt and in general made a mess of it.
Hold the flywheel with a tool and tighten the flywheel both properly to avoid issues.

Re: Lightened Flywheel - what's involved?
Id suggest doing some searches on this forum and the US one to get a feel for what folks using the light weight flywheel think.Beef wrote: ↑Wed Nov 28, 2018 11:05 am E.Marquez I'll take your advice - I know why they have flywheels but I don't know the true effect on riding, would it be more likely to lock the rear on changing down and not matching engine speed?

Personally I like the bikes reaction to the lightweight flywheel..
Faster rev up and More engine breaking work well for me.
An unskilled rider that treats the throttle like an on off switch the light flywheel may not work out so well.
Leaned over riding a 9/10's of traction and chopping the throttle will already cause the bike at best to stand up and go off line, if not break traction and cause a nice high side. Ham fisted throttle actions with any bike are bad, with less flywheel mass its more pronounced.
