FMX650?

[samwise]

I wonder how much work the FMX650 would need to be more trail-worthy?

It comes with:
45mm inverted forks with 218mm (8.6") of travel (Dommie 41mm RWU forks with 220mm - 8.7" travel)
Delta-Link Pro-Link rear suspension, 186mm (7.3") travel (Dommie 195mm - 7.7" travel)
Ground clearance 216mm (8.5") - (Dommie 245mm - 10")
Seat height 875mm (34.5") - (Dommie 865mm - 34.25")
Dry weight 165kg (363lb) - (Dommie 152kg - 334lb)

As the FMX currently has more fork travel, higher ground clearance, lighter weight and a similar seat height to the BMW F650GS Dakar (all it needs is more rear suspension travel), I think it could work - all it would need is a bigger tank, I suppose. :?:

Whats the mpg and tank range on the Dom?

Whats the mpg and tank range on the Dom?
Mine does about 17 km/l, though I can get up to 20 or so if I ride it like a car. :wink:

Tank range with the standard 13 liter tank on a '89 was about 110 miles until reserve. Now with the acerbis I get 200 miles...

(Yes I'm mixing units here, my brain thinks in km and my bike thinks in miles.)

[samwise]

When I was doing a few laps of the course, I got up to nearly 130 miles before hitting reserve - averaging about 55mpg, I think, all told here on the island.

[Rubberchicken]

Oh, right.

I normally do a lot of city riding and commuting, that usually gets me 17 km/l (47 mpg). When on a trip I get more as well, up to 60 mpg even, because of the long stretches.

Should be OK with just some knobbly tyres on there, I'd have thought?

[samwise]

And some spoked, larger wheels - especially the front one :D

It comes with spoked wheels as standard, doesn't it?

I know what you mean about larger wheels - but it's amazing what you can get away with on 17" wheels if you've got decent tyres on.


I've got an avon pro-xtreme rain front and an avon distanzia rear on my XR650R supermoto, and that's plenty good enough for all the green lanes I can find round here, as long as it's not too wet and boggy.

Most of the stuff I bottle out on due to the tyres is stuff I'd MUCH rather be on a lighter bike anyway! :lol:

Definitely a 21" front - I doubt the older fronts would fit the reverse forks and caliper though. Isn't the FMX down on power compared with even the last NX's? Those seem to have lost a few BHP copared with the first Dominators too. With work an FMX might be a viable option, at least in the absence of a proper NX replacement.

It's a miracle they managed to get that old aircooled lump through the emission tests anyway... :wink:

NXes are listed for about 40-44 hp, the FMX has 37...

Nothing that a bit of post-purchase work couldn't deal with :wink:

New Excel rim from Hagon of Central Wheels then? :D

Always got to have a pic for views :)

That'd be the way to go! It'd be nice to have the original for normal use and a 21" for off road (complete with proper nobbly), but I would settle for the 21". Actually, with engine mods and a different wheel, maybe this would be pretty good. I always figured Honda got it right first time with the NX, and then progressively made it too road-i-fied. With the better suspension and brakes of the FMX it could be better still...

A test I've seen a dyno test online at Motorcycle USA giving the XR650L 31hp (23KW) at 6000rpm and 29.7lb-ft (40.3Nm) torque at 3,800rpm

The FMX is listed as 37bhp (27.6KW) @ 5,750rpm and 38.6 lb-ft (52.3Nm) @ 4,500.

Would be interesting to see what the actual figure is at the rear wheel on a dyno.

My '95 used for the 17mile commute to and from work at legal speeds in a fair mix of traffic gives me around 60mpg and a range of about 175 miles. However, on long haul trips fully loaded, the range falls to about 160 miles. Just about the same time as my bum starts to ache.[/quote]
