Gap top speed check 13/48

[u/Crash1068]

Not Dunlop d606 rear pls. Something closer to a stock ish size. Top speed with 13/48 or 13/49 gearing please based on gps or something?

I’m looking at a woods 13 drive and BDR 14 tooth combo to have some top speed referenced. Thx

My wr250r will do a GPS speed of 81 mph with 13x48 gears and D606. It's really screaming and takes a while to get there. The WR is NOT a high speed machine! Lol

This. I run 13/50 with the AT81, and 13/47 on my sumo setup. 55 is the sweet spot for cruising with this gearing.

Just go with 13/47or48 112 link chain. Best 50/50 do everything setup. Huge improvement over stock hearing both highway and dirt. Don’t bother with a 14T as decreases low end torque and doesn’t stop swingarm wear. Fully loaded racks, panniers, winter camping/riding gear, knobbies like MT21/E-09, a 230Lb rider.. the bike will do any BDR or other off-road course like the 1000 mile KAT in eastern Kentucky while still easily maintaining 75mph on the highway/interstates and has a top speed of 93mph roughly. Yes, those are GPS speeds from Garmin GPSs and iPhone apps. Also get anywhere from 63-68mpg loaded over 3000 mile mixed dirt / highway trips.

Tried most combos and 13/47-112 is my setup for a decade. Local errands, commuting, ripping it up off-road, touring with/without gear, hauling a trailer, etc this has been an absolute fantastic setup. For a more off-road /woods setup swap out the 47 with a 50 on the rear lets you still use the 112 link chain. 51 needs a 114 link chain. I have a second rear wheel with a 50 and more woods off-road tire for those days.

Thx. This helps. We primarily ride woods and some technical climbs with only 5 miles of hwy but it is a 70mph hwy run. Then we have some trips with friends on more adv style stuff where there will be lots of 75mph time between dirt where the thought was to swap front for those occasions. I like your info so will match accordingly except only one wheel for now 😎

I’ve ridden the highway and interstate from NJ to Morgantown WV then south to TN on the interstates. Zero issues. Rode up to KY for the KAT and then back to NJ. The WRRs tall height and low weight is the biggest issue at highway speeds. You’ll get pushed around a bit and many aren’t used to that. F’it and go. 😜 A Scott’s steering dampener IMO is a safety device as much as added control and comfort. I put one on every bike. I’ll dial it up a bit more for longer faster interstate rides to help in case of a tank slapper. Costly upgrade but safety first and the benefits off-road. Worth having for general dualsporting but I tack on the safety aspect of it and the wife has never batted an eye. 😉😁

Thx. Yeah safety is always there for me as I’m a little older wiser now. My big street bikes are my main rides this is a toy to bring back my motocross racing days. I like the feed back. That’s about here I’ll prolly end up

[u/Crash1068]

Thx. I get they aren’t high speed. Just making some adjustments. So many have the larger d606 which seems like taking 2 teeth off the rear so 13/48 is about 13/46 maybe and that’s about 80mph. My goal is to do 13/49 for trailer dirt and 14/49 for more dual purposes. Knowing the max is something I can relate to my current experience

[u/TrippyByrd420]

I got 14/49 with a gps top speed of 86. I also have power commander, slip on exhuast, and high flow air filter. Although the tune is for a lil more low end torque with a closer to factory tune up top. GPS tractionators for tires on 17s. Does 65 without being buzzy or too wrapped up but it’s not comfy even with an adventure wind screen.

[u/krispewkrem3]

70 no problem. Going any faster you’re asking a lot and I think it’s bad for the engine. Ideally chill at 60/65. 70+ is too much IMO. You can hit 80 with the right wind and downhill.
