XR650R's gearbox for the highway

13 posts in this topic

A guy at my dealer said 650R's are terrible on the highway because they are dirtbike's. That's cool but if you gear it up enough, what will it be like? There was such a wide ratio in my 650L, that I felt like I was either lugging it too much of revving the crap out of it. Does anyone know where I could find the gear ratio's for these bikes?

As long as it's uncorked they make great roadbikes!!! They have way more power to pull taller gearing than the L model. Iv'e had mine up to 93 with stock gearing and can crawl along in the woods the same day.

Wait a sec..., really? Last time I listen to a dealer:bonk: So say you just went down a tooth in front and never planned on going faster than 60mph, how hard will it be revving at that speed? Does it have that massive gap between 1st and 2nd like the "L"?

For the highway, put 15-45 on the bike and don't look back. 4000rpm at normal highway speeds, and still pretty usable offroad. No real gap from 1st to 2nd. It could use a 6th gear so you'd be able to do it all, single track and 110mph, but the reality is that it's a 5 speed and wasn't designed to go through the really slow stuff.

I have found going to a 15-48 smoothed out the gearing, and made first gear more useful on the road, not decided yet on if its going to hurt me much on tighter trails...

Will the stock chain work for 15-45? If not what's the tallest you can go with stock chain? 15-47?

Yep because I'm running the stock chain with 15/48 so 15/45 will be a breeze.

Swapping to a 15t front sprocket with the stock rear lets me cruise 65-70 no prob and run away from anything with an engine in the dirt I have come across. It still feels like it will pull much taller gearing as I still have traction problems at WOT at anything below 70mph.

With the Right gearing the 650R is probably the best dual sport ever. It can do anything a mx bike can do, then its amazingly happy and super smooth on any road. The 650R just uncorked is one of the best engines ever made. I am running 15-48 and it works great as long as you don't need to go over 65 for too long. Anything taller than that will not be much fun in the dirt.

I'm wondering how the use of an auto clutch (Rekluse or Revloc) will help in the tight trails. Anybody using one? Ideally I would gear for 100mph and let the Rekluse do its thing on the goat trails. Is this just wishful thinking?:thumbsup:

Sean :ride:

Most dealers don't know up from down.

a XR650 will be just as home on the road as best that any dirt bike could be.

ive got 15-45 gearing and i just got my vapor computer on and have been looking at RPM speed,

its around 4200 cruising at 55 MPH, i find that with this gearing it's difficult to do the tight stuff.

Ive only had myn up to 88 MPH cause i have knobbies on it, and they dont work to well on the road:banghead: it was reving around 7 grand at 88. If i ever get the cash to do a Supermoto set up ill proble try 15-40.

I have 15-45 with the stock chain, it moves the rear tire back quite a bit but still works.
