Solid Axle vs Independent Axle

[vbbuilt]

Hi everyone! I don't ride a trike (I've a 2009 Victory Vision). I'm decided to move to a trike as my left knee and now right knee, are complaining. At 59, I know what's coming down the road.

Anyway, I've seen the new pics of the 2015 Tri-Glide and my mouth is watering. I've also been in discussions with Lehman out in Spearfish. Of course they're touting the benefits of their platform. They say the ride on a Tri-Glide with a solid axle is rough when compared to a comparably equipped Electro Glide conversion using their Limited Lean Suspension (Independent) axle.

Taking a 2015 Electro Glide model and upgrading with Lehman rear-end is pricy, much more expensive when compared to a stock 2015 Tri-Glide. Adding to my dilemma is that I live in northern Virginia and there don't seem to be any Lehman dealers locally. Question comes down to logistics and availability. I'd have to arrange to have the bike converted out at their Spearfish facility. That's time consuming not to mention more costly.

Question is to those folks who've ridden both. Any truth to Lehman claims about the axles?

Thoughts?

Although I can't comment on the TriGlides, I can give you my impression of a solid axle vs IRS (independent rear suspension).

I previously owned a 97 Valkyrie with a MotorTrike solid axle unit. I now have a Goldwing with Roadsmith's IRS. For me, the difference between the two is very noticeable. The ride of the Roadsmith IRS is much more comfortable with it's longer wheelbase and personally I haven't noticed any difference in the IRS handling the curves as compared to the MotorTrike's solid axle. The Roadsmith handles great and is very comfortable as compared to the harder ride of my MotorTrike. Now with all that said, my MotorTrike was a great trike! Never had any issues with either the MotorTrike or Roadsmith. I guess it all depends on what you're looking for. They say the solid axles handle better in the twisties. I haven't found that to be true although I'm not an aggressive rider either. All in all, the longer wheel base IRS trikes such as the Roadsmith and Hannigan will give you a more comfortable ride. I hope this information helps.

Rich has given you some very good information. My wife and I both love the ride of our IRS trike, and would go with IRS again.

See "Looking For Opinion"s thread. There are some posts on this subject there too.
There is no doubt that the IRS is smoother riding then a solid axle, but only on bad roads. As I stated, very seldom do I ride on bad roads (maybe 1% of the time) so the $5K extra cost for an IRS is out of the question for me. Maybe if the difference was a few hundred dollars I would consider it.

I'm still young (70) and don't have any health issues that would make me want an IRS, but for now I love my TG with solid axle.

Which ever you get, you will love riding a trike.

I also like the warrantee on the TG

Thanks for your thoughts!


Is there really that much of a noticable difference between the two axle configurations? I've never ridden a trike on long rides - only a test ride around that block. Obviously, a test ride around the block doesn't reveal much, so I only have people's opinions on which to make a decision. If the handling characteristics of the two axle configurations is minor, then my mind is made up.

The only experience I can relate to, is my bike. Longest ride is over 1200 miles. So my butt and nerves know how that feels. And of course, one can feel every nuance of the road surface, the vibration and heat of the engine, and other environment variables that wear down a rider. Those variables are present on a trike to be sure. I just can't equate what y'all saying about handling characteristics as I've nothing to relate to.

If you can test ride both types of bikes test ride them..straight versus IRS and you make the decision..

If you have a lot of crappy rodes in your area the straight axle is not recommended IMO..

Good luck..

In all honesty, I think Trikermutha's short advice is perfect!

On smooth roads, the solid axle and IRS are very close. But if you genrally rides on lousy road surfaces, definitely get the IRS unless you like being bounced around alot, lol.

In all honesty..I have the straight axle and like the Harley but with all the crappy things going wrong on it and the crappy roads I am thinking going another way on a bike..Been test riding another brand and liking it more and more the longer I ride it..

Any way good luck

There is a Lehman dealer in Martinsburg, WV. He works both Harley and Honda (other too). Check him out since you are so close. He can provide the information you want without bias.

I agree with trikermutha and rmrc51. I don't know about an IRS , but I think you can rent a TG at your dealer. See if you like it BEFORE you buy. I was lucky that my dealer has a demo days each year so I rode a TG for the whole weekend almost non stop. Then another dealer had a local trike day and had TG's and DFT's IRS trikes to test ride. That was when I made up my mind on the solid axle. I was impressed with the IRS on the "bad" road section but didn't see any difference on the good roads. I also like the warrantee situation by buying a standard mfg's product.

See if there is a DFT or other IRS dealer in your area and see if you can test ride one. Or check with bike clubs in the area and see if maybe someone in them might have an IRS equipted bike.

Obviously this is a very personal choice issue....I have had both, a 2009 Wing with IRS MotorTrike and I currently have a 14 TG. Goldwings just don't fit me well....I love the power and smoothness of the Wing and the IRS was great. However, I invested way too much money on seats simply trying to get comfortable....I had way too much neck pain, tried the risers etc....I just couldn't get comfortable and therefore my longer rides were very limited. The TG just fits me very well....6-0, 220lb with a 33" inseam. I have not had any neck or back issues and therefore I am enjoying the riding so much more....I live in a rural area south of Dallas, Tx and I do agree that the rough roads are not nearly as forgiving as you will experience with a quality IRS. I have 5,000 miles on the TG and I do not regret the move. I realized while I was typing this how little attention I pay to the rough roads. I have told others that I can not tell any difference on the interstates or state highways. For me, it is similar to the ride of a corvette on rough roads vs. a sedan on rough roads. Having owned a corvette, I can tell you it was not forgiving on rough roads but was great on the highways.

I wanted the security of an extended warranty and the ease of service so I choose Harley and have no regrets. It really came down to warranty and even more importantly, comfort....I ride solo....just some advice....if you test ride a TG be sure and do not judge the ride on factory tire/shock settings...I run 36 in the front tire, 12 to 15 in the shocks and 24 to 26 in the read tires.....either way, you will love a Trike....good luck

just curious, what brand may that be?? and what makes you like it more...?

LOL... Can AM 2014..

Me to Me to I looked at a Freewheeler at the local dealer (it had *just* been delivered to the dealership, and was parked in a dark corner of the place) so I sat on it, but not much more than that.

I hope to ride it on H-D Open House & New Factory York Plant Tours, September 18-20.

By then, BRP be out with their F3. Once I demo that, then I'll make an informed decision.

Keep me posted as I think I maybe buying a 2014 next week?? See how things go..

I really can not believe people say a straight axle can handle better then independent ?? Somebody should tell chevrolet to redesign the new corvettes & put a straight axle back in them like they had back in 1962 ??? JUST A THOUGHT

The first things that come to mind would be cost then more moving parts for the IRS. More chance of things going wrong. There isn't a factory Trike that has IRS, so no complete Trike warranty........For a reason to buy straight over IRS. As far as handling, the whole IRS unit depends on the front motorcycle length & suspension on the whole unit.
Some are using air on the IRS others are using spring over shock. Different weights set up different ways may out perform the other. I think with the newer IRS systems they can be set up to out perform the straight axle in corners. That being said, the straight axle will perform in the twisties from the get-go. Very simple set-ups.

[trikermutha]

On my DFT IRS trike I could drive just like I did on corners as my Triglide. Just the bumps get smoother on the IRS the Triglide will rock the bike over bumps..Both are nice bikes but as I get older my body cant handle the bumps like I use to with the straight axle ,even with all the added things to try to make it a softer ride..

Trike conversions come w/warranties.
The "donor" bikes OEM warranty can be affected!
