Interesting clip Stiggy  It would be even more interesting to see how one of your designed trikes compares. Pity we couldn't get a comparisons with says slugshot 's trike. Bet Kev's would be the outright winner on all counts, probably frighten the life out of the presenters in the process. nigel |

It would be nice to see a new threewheeler from Mev....maybe a front engined V-twin with an exo-chassis could be an alternative idea to the classic Morgan....here is a very rough sketch of my idea.  |

Or how about a rear engine, shaft drive, powering a front diff with CV shaft drives to the front wheels. As long as you don't try to push over 150 Horse, a Subaru rear diff flipped upside down should work.

As long as you don't try to push over 150 Horse, a Subaru rear diff flipped upside down should work. That would be a very interesting design concept. I also think that threewheelers are seen more as motorcycle based vehicles and a car engine is heavier and more cumbersome than a motorcycle unit. The positive side of using a car engine, would be to have a reverse gear in the unit that you won't find in a motorcycle engine, but you do find a few motorcycle engine with a reverse gear ( BMW, TRIUMPH, HONDA GOLGWING). If you want a mid-engine shaft drive set-up I would keep it as is and place in the middle.....but my idea was to simplify the chassis/bodywork, by using only an exo skeletal chassis covered with a textile( simlar to that of a Velorex 3wheeler) and use a classic front mounted V-Twin engine. In kitcar manufacturing, the expensive part is creating the moulds for the bodywork....if you eliminate the bodywork and instead leave it for bare essentials you have a very competitive kit threewheeler, just like the Tr1Ke has been for all these years. Mine is just an idea, but the possibilities could be endless but the end product should be affordable and look good. Cheers Italo |

This is a Honda S2000 engine mated to a T-55 5 speed running to a Subaru/ Nissin rear end flipped over driving the front wheels. This rear diff has been used in so many different cars over the years. Subarus, Nissin B-510, Nissin 260Z.... The rear cover can be flipped so it can be (over) filled a bit more. I have seen this diff survive behind a 5.0L Ford engine in a 260Z.  |

Re do a JZR trike naked and powered by a front mounted MotoGuzzi 1200cc would work too. mated to a "North-South" engine's FWD trans-axle driving the front wheels should not be too hard. But most FWD trans are East-West mounted.

This threewheeler looks very nice !....but I just think that it's not so simple nor is it affordable....it looks like a very expensive threewheeler. I was actually thinking of a more affordable threewheeler....and donor. |

As long as you don't try to push over 150 Horse, a Subaru rear diff flipped upside down should work. Why make it simple when you can make it complicated ?  We must also pay attention to the particular stability of the 3 wheelers. The center of gravity must be forward as far as possible. Dealing with the JZR with the 1200 guzzi, it's not a JZR, but a triking. But before them, I built my 3 wheelers with a 1200 guzzi and the rear wheel drive. Regarding the car engines, they have the reverse, but also more torque to take the car. The disadvantage is that they weigh much heavier than a motorcycle engine. |

Personally, I would like to get my hands on a bare TR1ke frame. It would be interesting to see if a GL1500 engine would fit. I realize the length of the engine/transmission would exceed the design of the R1 but then again if it were easy it wouldn’t be fun. What sticks in the back of my head is this: the Honda Goldwing engine has an outstanding history of longevity. You can litterally beat the heck out of it and it still will go for 200K miles or more. The engine has a built in reverse, all year models are carbureted with minimal engine electronics. There would be ample torque behind the Horsepower to even tow a trailer. In comparison to the Yamaha R1 the GL1500 is a low rev engine. It runs cool, has a very sturdy transmission and could be placed up front in a properly configured chassis. As far as the rear suspension goes, I would look at the GL1800 swing arm, strut, wheel and brake assembly. The wheel itself is a bolt on 16X5 and could be easily “Darksided” to match the two front tires.
Okay, reality check..... will this ever be built, probably not. However not everyone wants a hot rod to light up the tires and make a lot of smoke, or run at the track. I am pleased that my 180 HP YZF-R1 makes all that power. It has a mellow but menacing sound to the exhaust, especially when all that hot air (no comments please) is filtered through a pair of tuned mufflers. I simply feel the use of all of the excess GL1500 engines out there would make an excellent choice for a donor to build a trike from. I regularly see them for sale in the $2 to $3K range.

Roger, my take on a revised tR1ke. I'd relocate the front tabs for the A arms back a few inches to compensate for the longer Goldwing engine. Use a "jack Shaft" idea to move the steering shaft down to a rack and pinion but use different sized gears to change the ratio for quicker turning.
 and  The one thing bad about most Goldwings, and many other motorcycles is the charging systems. The Stators are (hot) oil cooled from the clutch area. But there are mod's to hang a GM car alternator off the front timing belt. The other issue with Carbratored Wings is they gum up and have issues. The mod it to take a "Weber" 32/36 DEGV and cobble up a manifold and runner system. With this mod the engine will gain more bottom end and gas mileage too. I can sand cast a manifold and runner in short order. It will need a water chamber so warm water can heat the manifold to keep it from icing. Just run a 1/4 inch (6mm) copper tubing around under the manifold and pour Epoxy to bond it to the aluminum (aluminium). I'd mount the Wing's motor in the back, run the driveshaft forward, mount a front differential from a Land Rover or such 4X4 up front and have two wheel power. Use two front hubs from a arm front wheel drive car like a Dodge Stratus and half shaft CV's. But with these mods it would not be a tR1ke, it needs a new name, "Hot Wing Express" ?

Dave
The fact that a lot of motorcycles are carbureted such as the GL1500 is a testament to their reliability. The GL1500 only has two of them. They are very easy to rebuild and not the fussy Kehin of the earlier GL’s. The reason I highlighted the 1500 engine it’s because it has an external alternator just like a car. It is direct drive and doesn’t rely on oil cooling. It has a reverse system, Horsepower and sufficient torque. Also, I’ve had a few of each model except the GL1800. The engines are durable, reliable, and love to run. You can load them down with luggage, tow a trailer, stack the passenger seat with a heavy hitting woman and then you climb aboard. If you are like me, you’re packing a few extra pounds as well....... The GL1500 will take you and your stuff anywhere you want to go and do it with ease.
