Flat tracker with a difference.

Any idea what the motor is in the Yamaha mate ie 650/750.

Pretty sure it's a 650 but I'm not 100% as I couldn't find anything about it. Found it here, there's some more cool pics too: http://www.vft.org/StreetTrackers/StreetTrackers.html

You might find something on it if you nose around that site

The Peoria TT,they hit it at 90mph at an angle and fly over 150 feet.I thinks it's the only TT left on the circuit now.

The XS650 is the most common base for a streettracker,most streettracker parts are made for them.There are plenty of performance parts,and 750 kits are not common,but they are around.My brother made an XS650 streettracker several years ago in Canada.He is making another XS650 project - this one has a Shell Thuet 700cc kit (big as you can go on standard liners) and a Shell race cam too(he used to ring up Shell and talk to him about the stuff he was buying).Shell Thuet built the flattrack Yamaha's for Kenny Roberts and Eddie Lawson.

The CB750 tracker is a bit bizarre,but no more so than my BMW R65....although the CB750 was used as a flattracker,but a BMW was seldon used (has been done though)

What about the 750 motor M?There was issues with them ie oil etc but anyone sort one out?(TX).

That was interesting link,I went back to the main page,then checked out the development of the NS750 and RS750 Hondas.There still seems to be confusion over the RS750 - they say it wasn't a reverse engineered XR750,that they took a Paris/Dakar Honda engine for the RS....saying it was 52 degrees.I still think it a little suspect that the XLV750 had a 45 degree engine,was air cooled and dry sump.They say they experimented with cranks until they found one that hooked up....the XLV750 had a 90 degree crank,I bet the RS750 had a single crankpin firing.I have a video of Ricky Graham winning his No1 plate,a couple of mile races,and the Honda sounds no different to the Harleys to me.

Just got back from sturgis,and went to the 1/2 mile grand national race only got three races in as it pissed down awesome lightning show though and they were quick.

Obviously, I am a fan of the XR750 look...and I must ask, now that I have found some enthusiastic and knowledgeable people; is an 883R a suitable base to build an XR750 replica ... or is the frame "too wrong" ?

The only thing better would be an XR1000.In the early '90's they ran a Sportster class,and all the pro riders rode them - Scott Parker,Ricky Graham,Chris Carr,and they were damn fast with those riders of course.They looked like an XR,but were just stock 883 Sportsters with the appropriate flattrack equipment.Of course the first XR750 was just a sleeved down 883 Sportster,complete with air filter.

A Sportster would be my first choice of bike for my riding,and a streettracker look - but I'm not paying the asking price,and not wanting a bike other people want to steal.The job can be done cheaper and without the paranoia.

Thanks. So if I bought a replica tank and tail-piece for the 883, it would line up on the frame ok ? How hard to adapt some 18" wheels?

You can get an XR750 seat to bolt onto a Sportster from Hotwing,but their site seems to be down on my bookmark these days....maybe a google would bring it up? The Sportster frame is narrow at the seat/tank area,I'd do a seat that takes advantage of that wasp waste look.
