Sprockets?

I love my 2017 VanVan. However, 99% of my riding is on the street. I want more speed in 1st and 5th. So...I've been looking for an aftermarket sprocket. The stock rear sprocket (64511-13G00) is 46 tooth. I want to drop down to a 43 tooth. I've spent the last hour looking on the internet hoping to find one with no luck.

I've tried to cross reference the part in hopes that another bike uses the same sprocket. Nope!
I looked for a 16 tooth sprocket to replace the front 15t. Again...Nada!

Maybe one of you guys might have better luck? Anybody?

It is quite difficult to find sprockets for this thing. It's rare not to find a few crumbs on fleabay, but that is indeed the case. So far, pretty much only Webike Japan has anything at all. Here's a rear sprocket they drop down to 44. I'd rather have a 16T front, but haven't seen that yet, but guess this'll have to do for now...

I couldn't find any sprockets either and so I took the measurements off of mine and had a 43 tooth sprocket made. I got the bike up to 70 mph on the freeway with no problems. The bike handled great at that speed. I'm pretty happy although I will probably go with a 44 tooth sometime in the distant future. I think I got a little greedy with dropping 3 teeth. The bike needs to be on a flat road in order to get it up to top speed. I can take the bike up to 45 mph in 4th with no problems.

Yes 44 toothed rear is best for street/dirt. I got mine from sprocket specialties. Bolt pattern is the same as on the vanvan 125, just request 520 chain profile.

I bought mine from webike japan a 43t rear sprocket. I checked the speed with my GPS at 70 mph. Good cruising speed at 60 MPH. No big change on the dirt.

Just looking for new sprockets for my 200, after 3000+ miles the chain is very tired. Did a trip round Ireland last year and ended up having to adjust chain everyday.

Having hunted round it appears that JT (in the UK at least) do replacement sprockets that fit.

Unfortunatly they don't do the stock ratio of 15/46. The largest rear is 44, which will slightly increase the gearing but not by much and I think I'd be happy going that way rather than down gearing.

I down geared my 125 VanVan as it wouldn't rev out in top gear but I think the 200 will pull ok.

I'm in contact with Wemoto.com and I'll look at getting a set to try but am fairly confident they will fit as they are available as an upgrade to replace the standard 428 chain on the 125.

Part number for the front is JTF422.15 and the rear is JTR1826.44

The front comes in 12, 13, 14 and 15 and the rear in 39, 40, 41, 42 and 44 so most ratios could be produced, in fact 13/40 is also exactly the same as standard.

Cheers

Mark

Good information . Must admit though it seems that the oem chain must be poor quality for it to wear so quickly, so larger size or different brand might be the go.

An update...

I've fitted the 15/44 sprockets and a DID VX2 GB chain, the 112 link standard length was too long and the adjusters were almost all the way back so I took it down to 110 links. I had to move the adjusters all the way to the front but the chain did go on.

It is definitely more relaxed at faster road speeds, although on flowing roads at 45-ish it feels like its now in between gears, 5th feels like its too low and 4th is a bit revvy.

We have a week away next week so will see how it is on a proper run.

I think one reason for the poor chain life is the lack of a cush drive on the rear wheel, probably why the OEM front sprocket is rubber mounted.

I picked up a 43 tooth rear sprocket from a company here in the US called Sprocket Specialists...Motorcycle Sprocket Specialists | Stock & Custom Sprockets
Nice sprocket made from military grade US aluminum.

On a sour note. As far as a front sprocket goes, they only had the stock size of 15 tooth.
