Tony whatever else we may be most of us are true motorcycle enthusiasts and love seeing stuff like this, I love watching others builds and some times i get inspiration from others. This is exactly the type of bike most of us would have loved to have owned when we were younger (age, bad backs, rheumatism, knackered knees probably would stop some of us now). I like others am really looking forward to watching how this progresses.

Before the chassis was built i had a few talks about which type of forks to use and i also contacted a suspension company called HK Suspension. It was agreed to use a set of OhlIns forks from an Aprillia. Because i was using the TZR rim in the back i used an old type R6 rim which i already had for my LC (both are 3 spoke type rims). How ever the diameter of the Aprillia wheel spindle is bigger than the R6 spindle. Trying to find a wheel bearing which could fit in the R6 rim and accommodate the Aprillia spindle was a no go. There was how ever a wheel bearing which was a tiny bit bigger. The bearing pockets in the rim were enlarged to fit the new bearings. Center to center distance of the Brembo's and the R6 disc brakes are the same, but the Aprilia discs have a larger diameter. This bike will not be that heavy so after seeking advice from forum members (you chaps) i decided that 300mm discs were big enough. The brembo calipers were machined down to give the correct clamping distance.  |

If so (as suspected) your going to end up with big offset front sproket. The spokes are thinner than the R6 so won’t match exactly but close enough. Jon |

Yep your bang on with the 3XV rim Rob, but after a lot off talking to to people and imming and amming i decided to fit this type of wheel.  It's a Marchesini rim |

Much lightness and a little wider??? 5.5 wide and a little lighter. I also think the profile of the 165 tyre looks good on a 5.5 rim. I want to keep the bike as close to a 100kg if possible |

My Marchesinis are uber light from memory the 2 without discs tyres and sprkt etc are about 3kg in total considerably lighter than the std lc. However mine are off an Rs125 racer so they are skinny, loads lighter than stock equal less unsprung weight equal good stuff
100kg is some target, I would be interested to get mine weighed.

Still not bad though Tony, do you know how much the motor weighs approx? I know with mine the heaviest thing about it is the beer drinking pie eating riding

I need to get some scales and have a measure. At present with empty engine, tank, seat, wheels with brakes, rear-sets, handle bars, carbs and cable, exhausts and radiator i can lift it on my own fairly easy and walk around with it, but i am used to lifting heavy weights at work. The engine internals and fairing will add a lot of weight. |

Nico asked me to find a rear brake disc and calliper because the parts i supplied were too heavy. This was proving a little more difficult than i thought, again a forum member came to the rescue. Due to the nature of my work it was taking a long time to supply the parts to Nico and Iwan. Here is a weight comparison between standard and lightweight discs.  The left disc is a standard disc the middle disc is a lightweight standardish size disc now sitting on my 4LO and the right disc is a very light disc with the dimensions Nico wanted. The tiny Brembo is a Knock off but it will do for now. Thats two YPVS cylinder nuts next to it to give you a comparison of the size. 
In the same time i was looking for a disc etc Nico sourced the disc below, wavy is not really my cup of tea but i will keep it on the bike as it is the style that Nico Baker uses. This is also very light.  |

The chassis has now been built up onto its wheels so the next thing needed was a seat unit. The workshop needed to fit the seat unit so they could see the space left for the fuel tank. Kees and i looked at lots of pictures on the internet and it came down to a TZ 5KE seat and a Honda seat. I decided to let Kees have the final word so the TZ seat was choosen. Later i asked him why he choose that type and he said that there was room for a brake light!   When i saw this i really did not like it. Talk about fat arse. With the big bum fitted the bike could be measured up for the fuel tank. The fuel tank is fitted with a pingel high flow duel outlet tap. The inside of the tank has special baffles to keep feeding the fuel to that hungry engine when doing silly cornering and braking manoeuvres. Far beyond my skills  I made a picture of Kees sitting on the bike in the tucked down position. I then realised the seat was very functional so now it can stay in place.  |

Are you going with the 3XV rear wheel now?
I did wonder what tank you were going to use as the spars were very angular.
Tank looks great BTW.

There looks a lot of clearance under the engine.
The swingarm looks angeled down compared to the front swingarm pivot point....is that to get more squat under power???

Sorry Rob i don't Know much about motorcycle geometry. It will be going back to Nico Bakker for some adjustments one of these will be the geometry. I want to build the brake lines but first it has to be at the correct height etc. i personally think it looks to high at the front. |

There looks a lot of clearance under the engine. The swingarm looks angeled down compared to the front swingarm pivot point....is that to get more squat under power??? I thought exactly the same. I can only imagine that Bakker is building for a track bike with maximum ground clearance. Makes sense if he recommended a pipe up both sides as that is an option on a twin. The V4’s may have struggled with having the lower expansions too long if either side to get the tuned length, and against regs if either side; so the GP style made sense. Became a bit of an image thing IMO. Might also explain the want to mount the rearsets higher? That said this bike is bound to handle far better than our hybrids on a track. As Toby says though he’ll not feel comfortable to use it to it’s limits, and I doubt many of us would either? Jon |

Absolutely love the bike , well done , in my humble opinion though , I think a Honda rs 125 seat unit would suit the bike better than the Tz seat unit . 🤔
