Hi,

I'm in Australia and considering the XSR as a learner bike. I've been learning on a CB500F and now I have a clue as to the style direction I would like, this seems to be the bike for me.

In Australia we have 655cc engine for the LAMS (learner) market instgead of the normal 689cc. There is also some option to get the full spec engine, but this would negate my current licence needs. As I believe this is not a drive by wire like the MT07 / FZ07, I don't expect the power restriction (limits the throttle input) would work on the local XSR.

Interested to know if anyone knows if the XSR700's full power (from the smaller engine) can be achieved with just a tune. There may be a bit more to be had with a intake and exhaust, but my main concern is dumping ~$10k(aud) on a new bike, only to want more when I'm off the restricted licence.

A local tuner reports ~64hp atw from an MT07, if the torque from the 655cc is near the 689, I think it would be plenty of bike for me.

Welcome to the forum! You can always check and see if there's a used xsr700 around. You can save a bit of money that way and put it towards the needed exhaust, throttle derestriction, air box mod and PCV for more power.

The XSR is exactly like the MT-07 in terms of restriction and throttle design. These bikes are VERY alike.
Thanks, I may check out the FB thread if I can get past my anti SM feels (forums are as close as I get).

I have read (or more so heard in YT vids) that the XSR was not drive by wire, but I may be confusing the XSR700 and 900, where the 900 seems to be cable, like the 2017 MT09.

Cheers.

Similar but not the same as the mt-07. Same throttle plate (you can buy a homemade one on eBay or cut off the stopper) and throttle stacks/intake (you can dremel them open or buy from the HO) but the ecu is different and needs remapping. Apparently doing the plate and intake stacks without remapping the ecu will make it hard to keep the front wheel down.

a tuning joint in moorabin quoted $850 instead of the $500 for the mt07 because they hadn't done the xsr700 yet. You can't read a Yamaha ecu without destructively cutting it open. Once somebody does this (and voids their warranty) the tuning joint will be able to make a tune file and write them for everyone else at the regular $500 price. I wasn't brave enough to go first.

From what I've read the lams mt07 only picks up a few hp from a tune and better exhaust. There is 20hp to be had from intake and plate. The tune is for rideability. The stock Japanese pipes are very well tuned, and the akro high pipe actually reduces hp. Dealers make a big deal out of minor gains from pipes because that's where they make their money.

If their is a high output version of the xsr700 in Australia I will be pissed off. I purchased mine believing they only difference was the 6% capacity loss from the cylinder sleeving. I didn't expect the 30% reduction from all the other restrictions. But that said, the bike is a cracker to ride around town and through the hills. Everyone says you only notice the difference on the track.

cheers.

I'm not fussed with peak power, one of the reasons I like the MT / XSR is for the torque'y engine, if I was after outright HP, I would be looking at a 4 cyl.

Coming from turbo VW / Audi, its nice to be able to ride fairly fast without having to redline or dragging 250kg around like some of the cruiser bikes (which I should ride before I trash them too much).

I completely agree with you mate. But you know what, I think people are mixing up what the XSR is about. It's about the style, the fun factor, the ability to customise, something to cruise on and pull up at cafes by the beach, that's exactly why I bought it. If I wanted a go fast bike I'd have bought (another) one. The loss of such a small % in HP and torque isn't worth the extra money they will charge for it!

So to you Mr @beeez, with all due respect. Go buy something else!

Hi,
has anyone on here just removed the throttle restrictor without doing the other performance mods?

Yep, I've done the derestrictor plate and have akra carbon exhaust. Bike runs superbly, seems there is some sort of electronic restriction in 6th gear as it tops out around 165kmh but can get well into 170's in 5th. Down low is where it's most fun though. I havnt dyno'd it to quote % improvements in hp etc but the thing feels a **** of a lot better with no adverse effects to date. Have been running the mods for about 4mths, probably at least 4000km. For what it's worth my mechanic says the airbox job isnt worth the effort. I dont plan on keeping the XSR long term as I'd like to step up to the MT10 once on unrestricted licence.
