Suzuki with shaft drive motorbike engine around 800cc

Sun Oct 14, 2012 4:17 pm

Just wondering if anyone knows of a shaft driven suzuki motorbike engine that could be used in a suzuki hatch or MB up to 800cc and liquid cooled. Id like to use a carry diff rwd and prop shaft all the way to the back from the front and have sequential 5 speed box. Gonna be club reg so engineering wont be an issue othewise would go for 900cc or bigger engine.

I'm not right across Suzuki bikes, but I think the only shaft-driven models are the Burgman and some of the larger V-twin tourers. The Burgman has a CVT transmission through.

Didnt know about the Burgs! wow heavy 269kg dry for the 650cc one.

Im going to have to settle for any brand of motorbike engine as long as its a small four with shafty

Not many 4 cylinder ones with shaft drive in that capacity. A shaft system is a lot heavier than a chain system so it's usually reserved for bigger Tourers and Cruisers.

Best I can think of is the v twin from the M90 and C90 cruisers (VZ800 and VL800). It's a cracker of an engine , smooth and torquey, with EFI and very reliable.

would really need to be a conventional V twin not a side on one, Id prefer a single thumper 650cc single instead then but hard to find with a shaft only drive.

Atm since its looking unlikely to find a suzuki engine Im just going to look at engineering another suzuki auto motor eg.
560kg x 3 = 1680cc NA motor limit
560kg x 2.5 = 1400cc turbo motor limit

The place above supplies new motors 1 minimum order and if I can get a gbox
it will make a nice rwd midmount platform. They consume 5.5L/100km.

or just run a twin inline at the front with 5 speed and 600cc 44kws

What do you mean by "conventional" and "side on".

Why would it need to be a shaft drive motor? Chain drive motors still have a splined output coming from the gearbox. Should be able to adapt a shaft too it somehow.

Conventional is as per Harley-Davidson with North/South cylinders, "side-on" is East/West. Most shaft drives I have seen have the crankshaft inline with the driveshaft & have inline, East/West twins/quads or boxer engines. I have never noticed a "conventional" V-Twin driving a shaft with the exception of Harley trikes. Keep looking - I don't know heaps about bikes & likely missed something.
So many delays to getting my MB back in order with 993cc & 5 speed transaxle... neighbor issue gone, donor shell up on rotisserie, new sheds on the way.... another project also..

yep thanks for the clearance, Side on is harley conventional twin as opposed to motogucci vtwins and bmw boxers but sequential gearbox was the main interest and lightweight but there is little suzuki available to suit in water cooled so will have to keep looking or just go the other way with the links of engines stated above.

Tons of the Japanese cruisers with a "conventional" v twin run shaft drive. If anything, the east/west v twins would be a rarer find (I can't even think of one off the top of my head).

Problem is most of the cruiser motors are bigger (1200cc up.)

If you go to www.mrcycles.com they have all the parts diagrams for most jap bikes. You should be able to look up the exploded views of the gearbox output and shaft system to see how it all works and whether it'll work for your application.

The ultra reliable Honda CX500. Own one, had three.
Mega expensive Moto Guzzi. (Italian, spares are heaps !!!)
Aust made Howard (agricultural farm implements) Rare.

All have 'conventional' style V-twins. The CX and Guzzi are shaft drive from the factory. Quite a few peeps have done a trike conversion on these. Some have also converted them to chain drive. (so they can change sprocket ratio).

Hope that helps a bit. :D

Don't worry about if it came out shaft driven or not. Just make an adapter plate and bolt the tail shaft onto where the sprocket goes. I did that in my Mightyboy and it was the best thing I've ever done. Put a fuel injected Honda CBR 1100cc in the front of mine running a two piece stock tail shaft out of a 2004 Nissan Xtrail going into a chopped down ford escort locked diff with 3.54 ratio running the 12" Suzuki pizza cutter tyres haha. 165hp! Smokes the tyres all day long. Does rolling burnouts at 80kms/h and I haven't had a car beat me in it yet! Don't go the carry van Diff. It doesn't work I tried it. The ratios stupid like 6:1 and it does like 40kms/h in top gear. Even the ford escort Diff at 3.54:1 is too high. The bike engine is revving at 5,300rpm sitting on 100kms/h. Need like a 2.7:1 chopped down borgwarner Diff I reckon
