125-200cc Wide 5 speed inquiry...

I'm looking at a 1999 WR250 gear set with shafts on ebay. The price seems high to me, but I'm pretty sure that year had the wide ratio 5 speed. I think it would be a good tranny for the riding I do. Has anyone else done the 1999 tranny mod in a newer WR? I know the 6 speed is a popular mod. They seem to be even more outrageously priced though. Would I also need the shifter shaft? Any thing else. Any help is appreciated. Thanx.

Wallybean (Walt) has done the wide ratio 5 speed swap more than once. I'm pretty sure you will need all the shifting stuff, drum, starwheel, starwheel detent and selector shaft.
What do you see the 6 speeds going for?

There's a whole bottom end with 6 speed tranny on ebay for $780 plus shipping. In my opinion, that's pretty steep for something that's possibly damaged to begin with.

The 5 speed that I was referring to doesn't come with the shifting components. This mod is just too expensive, but I really need it. I found one on here (cafe) for only $250. But, the seller won't ship to Canada. I'm not sure if I'll ever find what I need for a realistic price.

The wide ratio 5 speed that they installed in the WR250's from 99-01 is a direct swap in for you 04 CR tranny. It uses the same shifting mechanism, drum, forks, and shafts. Really simple swap. Just re-use all the shims that are on the outside of the countershaft gear cluster on your current tranny with the new tranny. The shims are sized to fit with your cases. There is a pretty good jump between 4th and 5th but other than that it is a really good tranny for all around use especially if you are going to do any fire roading or long transfers between trails. You can cruise all day at 60-65 with that tranny. With stock gearing 5th is good for 85+ top speed.

Obviously, I preferred the 6 speed just because of the consistent gear spacing and virtually the same top speed.

easiest to buy a whole 90-99? 250 or 360 whole bike to get the tranny. my 95 360 is currently running a 91 250 trans and clutch..

Keep looking there are deals out there.
I bought a 93 360 bottom for 350 and sold my stock CR tranny for 250 but that was a couple of years ago.
Earlier this week a bought a low hour 99 360 complete bike for a thousand with a PWK and FMF Fatty. It needs a couple things but I have the parts to fix it from the 93 bottom.

Thanks for straightening me out on that Walt

I will be doing this mod very soon, it's going on a wr300, I'm hoping it will be great on a 300, as I've heard it's a bit gappy on a 250. I have the complete set of gears required to do a wide ratio conversion. firt gear is the same on both boxes so I am wondering though if I can swap the cogs without removing the clutch? That is only splitting the main cases & leaving the clutch housing intact. Has anyone done this mod?

I m not sure as i haven t done it yet- but here in germany are lots of WREs been parted out. These gearboxes have different (wide ratio) gears- so these might be the way to get around the close ratio of the newer 125s ...

I would buy 6 speed tranny.
I dont know how the gear is on newer wr's, but the 5 speed on my bike could be 6. Its like there is something missing, and that sir is the 6 gear.. Bet it would suck if you buy a older 5 speed tranny and feel the same way.

I've used these ratios found in the repair manual. Then I just plug the numbers into gearing commander for accurate speeds.

This is in the 125-200cc section at this time.

My idea of wideness of ratio is how first compares to highest. Admittedly I started out with a BMW twin where the sidecar box changed first second and third so not only did the overall ratio get wider the individual jumps got larger.

I ran the numbers from post 11

2.679 92-02 WR/WXE360, 92-98 WR/CR/WXE/WXC 250 6-speed Semi-close ratio transmission
2.571 99-03 WR250 5-speed Wide ratio transmission
2.034 99-04 CR250, 04+ WR250/300
the four stroke older single cam six speed available during a lot of this time frame

Here is a link to advrider.com where single cylinder bikes are listed for comparison. One can detect a rounding off error as two husky bikes with same transmissions get a minor difference.
"The first number is the first gear ratio divided by the top gear ratio. The bigger the number, the wider the gear spread."

I am willing to allow a bit tigher ratio to earn "wide ratio" for a smallrer bike but come on guys. wr=woods racer

One thing you are over looking on the 90s six speed is that they came from the factory with a 15/48 or 14/48 sprocket set up, depending on the year/model. Most newer bikes come with a lot closer final gearing set like 13/50 or even closer. When using the factory gearing with the 90s six speed you did have wide gearing.

I am selling a 6-speed from a 1992 in the classifieds: http://www.cafehusky.com/threads/wide-ratio-6-speed-transmission-92-wxc-fits-250-300.46527/

Price is negotiable, have (surprisingly) not had much interest.

I don't know what the price is for the set you are looking at on ebay.

PM me if interested.

You can't really compare to the old single cam 6-speed (same or similar to what is in my TE610). It is SUPER wide. Even though it has 6 speeds, the spread between gears is often too wide. It is one of the widest transmissions I have ever ridden on anything performance oriented. I often wish it was narrower.

The older 6-speed is more than 30% wider than the modern transmissions, people call it wide ratio because, relative to what comes in the bikes now, it is.

My (main) intent was for the reader to click on the link and see 20 or so listed out. I believe the 2015 husky 250/300 two cycle will correspond to the ktmxc-w in that list.

my friend had put one of those italian single cam trans installed in an 84 250...its wider than my zrx, or so it feels that way.

Don't forget that final gearing has nothing to do with transmission gearing spreads and ratios between gears.

You are correct, I was just point out that from the factory the gearing was nice and wide and very usable. Both you and I have 1 of these and I think it is because they are good.

On your 610 you can just install a smaller counter shaft sprocket and still have plenty of top end.
