fuel ecomonmy

i have a 06 wr450f and i wanna ride it bout 500 km on the main road for a road trip will this hurt my bike and how far should i get on a tank of fuel

[DeanMember]

Gyday Whanny,you should be able to get about 100 – 140 km on your tank if you raise the gearing and dont get on the main jet to much. WRF’s arnt really suited to the road work as there is no give traction wise and it can place some strain on the gearbox.I have heard of several that have gone in the WRF. You can get a mod done where flexible rubber blocks are built in to the hub. (cushion drive I think its called)

Personally I wouldnt do it. Hope this helps

I agree with Ollie mate :blink:
WR 450`s are not built for the roadwork :unsure: Will go the distance, but will not like it too much at all I should think.

Maybe you should but a Super Commuter It does the road trips with ease

CushDrive Hub would be an expensive mod to allow road riding for sure :huh:

Hope this helps,,,

Mate as far as hurting your bike goes, it shouldn’t be an issue so long as you don’t have it pinned the whole way. Can’t help you with fuel economy though, it depends on your gearing and what sort of speeds you will be doing, you could maybe just work off your trailriding K’s and add a bit for the smoother riding. Depending on how much time you have before the ride you could consider one of the rear tanks from Nomad tanks, I put one on the DRZ for a long ride, it’s still on I just don’t fill it unless I need it, the one I bought is 7.5 litres so all up I can carry 21 litres.

Yeah cushion drive hubs are needed on WR’s ask the Yamahas in the condo etc they spit gearboxs out there all the time without them as do the CRF’s

They used to come with stickers on them from new stating not to use them for prolonged use on road.
They do blow gearboxes when used this way, my brothers 426 threw third gear on a long transport but had about 10,000 ks on it at the time.Yamaha dealer would probably advise against it too :dry:

I’m not sure what would be worse after 500k’s your bike or your backside :laugh: and i’m guessing tar riding

I have a 15.5 ltr tank on my 450 and am running 14-46 sprockets. On my last big ride (450km for the day) on the return trip from Colo Heights to Teralba I did it on a tank.

A lot of this riding was through the bush taking in all sorts of terrain from single to fast twin and a little bit of road in between.

I know that this doesn’t really answer your question about on road KM but like everyone else said with the right gearing and not being on the hammer all the time you could probably get around 100 to 150km from a standard tank of fuel. But a lot has to do with riding style too I guess.

But 500km on a WR450 on the road – good luck, your arse is going to need it at least.

Pack a 2litre coke bottle of fuel in your back pack , I’m on a 250 and lucky to get 80-90kms out of it. As long as your not doing phycotic speeds on the road I don’t think it would be an issue other than fuel.

Cheers
Chris. :laugh:

I would be more concerned about the gearbox issue stated above.
A mate of mine trashed 3rd gear in his WR450 and the onlt road sections he ever did was short transports during trail & ST riding.
The repair job cost him $1800 :S

Is it just Yamaha’s and Honda’s that have this problem? I appreciate it’s tougher on any gearbox but am interested it seems to be an issue with certain bikes more than others.

I had better stop doing so many road K’s on the 450. Not always on both wheels either which won’t be helping :ohmy:

[GregMember]

No not so much Moto, the only experience I have with it was when I raced the condo 750’s and with talking with other race teams such as GHR and the Sam Laws Yamaha race team.
The shock loading at high speed is what destroys the gearboxes, they are a basically a motorcross gearbox built as light as possible and the shock under load then free and then under load is the destroyer.
GHR had to run cushion drive hubs on there CRF450’s but never with their XR650’s and the 650 puts out heaps more torque. But the 650 gearbox is huge compared the the 450.

When I rode to the cape, you would be traveling at say 120kph and you could feel it speed up and slow the whole time as it gained and lost traction all the time this would load and unload the drive all the time.

The harder you ride the harder it will be on the bike, most of us probably wont ever have the problem but the potential is there

For between $5000 and $6000 he could get a XR650 conversion for the Yammy and not have to worry at all
