Dual Discs XJ750 Seca

So I am a bit confused. Was it all Secas that had the dual discs and the Maxims got hosed with only one disc? Or do I have a freak Seca with dual discs?

Hard to sort out what is what here sometimes.

 

Maxims didn't get hosed, Seca's got upgraded
"we" also have air adjustable forks, anti-dive valves and rear rebound damping adjustment.

"our" 750R was only made for three years and they all had dual front disc. I'm no expert on all the other sizes and years.

 

well i know i feel special, how about you guys?

 

the 750 seca rh was more or less the boss 429 cj of the xjs, a thinly disguised race ready bike while the maxim was closer to the 429 cougar spoiler, more for looking cool, the smaller rear wheel makes for quicker acceleration but the milder cam made them equal in the 1/4 mile as opposed to the seca was nearly 10 mph faster when redlined in 5th. There was a difference in horse power. But yamaha like nearly every other motorvehicle wanted more money for a faster bike (xj 900 which was 10 mph faster than the 750) with the same cases and shouldn't have been much more expesive to build.. Did it ever occur to anyone that the 250 v-star has a govener set at 85 so it won't be faster than the 650 which weighs 200 more pounds and costs nearly twice as much? You get what you pay for, thats why the seca with the same motor cost more money than a maxim of the same year. Cast iron and aluminium costs the same per ton regardless of whos name is cast on it. I'm slowly converting my seca to a maxim but keeping all of the seca upgrades cuz I want a cruiser that runs like a dragster. Look out evo fans there's a new outlaw in town!

 

Padre, nice conversion. I had the same thoughts about a virago but it's kinda a shame to waste all those cool upgrades on a dog of a V-twin.
Also the gearing is just right for a hell of a dragstrip weapon when you consider it finishes the 1/4 right at top speed.

Zookie, hells yeah I feel special. Schooter is helping that special feeling with those dyno drag vids.

 

I can relate to the Ford comparisons! YAY!

Thanks MB for giving me the skinny. Just got my bike running today and I can tell it will run like a scalded dog.

Coming from a YZF600R, I am curious to see how this bike will differ in the power department. I am betting more torque for sure and a wider power band.

 

but it's still shaft drive...

 

I guess I am missing your point here.

 

it's an extra 25+ lbs of unsprung weight that we add to the ass end in the name of low maintenance. It came about in an era when burlier and burlier bikes were developing a tendency to break low tech chains. Some of the smaller Seca's in certain years (Fitz's 550's) had a chain drive and are nimble for it. These days chains are plenty strong and the shaft isn't really a necessary work around for the engineers but a lot still like 'em if for no other reason than the maintenance interval seems to consist of peaking in there every 10k miles and confirming the oil is still in there. Some of the big mileage beemer guys I know consider even that to be babying the damn thing. "change the fluid every 70k miles whether it needs it or not, hardy har har" and that sort of thing.
IMO it beats the hell out of effectively re-truing your rear wheel tracking every 500-1500 miles.

 

All those reasons you said above are reasons why I like the idea of a shaft drive bike. Low maintenance and super strong. I am a big guy so wearing out even the toughest of chains, I still wore them out in 6-8K with proper care. When I ride, I put lots of miles on my bikes. So changing chains more than once a year is just stupid for me.

I agree about re-truing the rear wheel. I hated maintaining my bike's chains. Boo!

 

To each their own. I too never realized what a PitA chain maintenance was until I didn't have to do it any more. I didn't mind it at all at the time but now I'm a convert. I think if the modern equivalent of my Seca came out today with a shaft and a competitor issued a chain I'd go for the chain. It's a sportier setup. It's all good in a cruiser like a maxim or Virago though. Being the vintage it is I don't expect blinding speeds and lazer cornering out of this "sport tourer" so I'm quite satisfied.
