Renthal Flat bar handlebar conversion.

Post by sirch345 » Sun Jun 04, 2017 9:02 pm

I finally got around to doing the Flat Bar handlebar modification :D
What can I say, I absolutely love it :D I should have listened to Al (AMCQ46) long before now :lol:

The reason I have carried out this conversion (now that I'm getting on a bit) is mainly due to the pain I am getting in my neck and shoulders which I am seeing an Osteopath for, although I think the problem is more than likely due to wear and tear, I hope I'm wrong.

I gathered up the bits I needed over a period of time, leaving the Renthal Ultra Low handlebars to be purchased just before the conversion, plus the new Venhill stainless steel braided brake lines. Using this set-up I haven't needed to trim the fairing due to fitting 3mm steering lock stops. I wanted to see if I was happy with this mod first before chopping the ears off the fairing. Now I know I am happy with this mod I will most likely trim the fairing, as this makes the fairing lines flow better with this mod as Micky (mik_str) pointed out, plus it will cure a small problem of the clutch master cylinder reservoir just touching the fairing on full righthand lock. If you study the first photo you will see the metal gizmo that stops the reservoir top from unscrewing has been removed along with it's fixing screw.

I also have kept the original top yoke by buying another one, cheers Mac (MacV2), then drilling that for the bar risers. I fabricated two pieces of aluminium flat bar (8mm thick by 25mm wide) to reinforce the riser mounting points. They had to be individually cut and shaped to fit the underside of the top yoke. I know some of you probably wouldn't bother with doing that, but IMHO this helps spread the load. I did all of this before I took the bike off the road to carry out the modification.

I made up a patch lead for the horn as that wire is too short for this mod. That left the original wiring as it was. It was just a matter of crimping two female spade connectors to one end of a short length of double feed cable, and two male spade connectors on the other end.

New brake hoses are required for this mod as the standard original ones are too short.

The original clutch hose is long enough with my 3mm steering lock stops fitted, but I had to make a new bracket up so it sits higher than the original mounting point. It may not be long enough without my 3mm thick steering stops.

You also need a different set of bar end weights as the Renthal bar internal diameter is smaller than the VTR original clip on handlebars.

Looks fab Chris,
Where did you purchase the Clamps from?
I did the CNC route previously, but not doing that again. i'll be pulling bits together over the summer in prep for the Winter strip down and rebuild.
Don't hassle me
I'll get there at some time

Thanks Paul :thumbup:
Most definitely. At least you know what I mean Paul :wink: :lol:
It was a bit time consuming making up those reinforcing pieces to fit under the yoke, but I feel happier with them fitted.

Thank Al :thumbup: I was grinning like a Cheshire cat for the first couple of miles on the test ride out, I couldn't believe how good this mod is.

Before you all rush out and do this bar conversion :lol: I realise this it's not going to suit everyone, but it suits me fine now at my age :thumbup:

I found on the first ride I was over doing the steering with the more available leverage from the Renthal bars compared to the clip-ons. I'm getting the hang of that now.

Thanks Grumpyfrog :thumbup:
I came across the risers on Ebay, a snip at £30 I thought. I've had them for years as I knew when I wanted some I'd be struggling to find some at a reasonable price.
They are like the ones below, although M&P have sold them and Jonny Rocker sells them on Ebay.

These are the ones I purchased. I had to machine off the half round piece to give a flat bottom on each riser. The risers raise the handlebars 19mm (3/4") from the top of the top yoke.

Update.
To compensate for less weight over the front end with this handlebar conversion, I have now dropped the yokes down the fork legs by 2mm more. This has brought the handling almost back to how it was with the Honda clip-on handlebars.
I'm well happy with that :D

Hey Chris why can I see light through the front air vents. Are you missing some plastic from the inside of the fairings. Iv'e been eyeballing the 3" and 4" Apex Risers. They are seriousley teasing me but I'm going to hold off for now. Iv'e spent far too much already.
